When three Hawaii flights to/from San Diego, all experienced flight diversions crossing the Pacific. What causes these flight diversions?

Within 48-Hours, 3 Alaska Air Hawaii Flights Divert Over Pacific

We don’t know about you, but we worry anytime there is a flight diversion on a Hawaii flight. The cause of the following diversions isn’t clear. The most obvious are mechanical, medical, and passenger issues, as detailed below. This all happened last week, within a 48-hour period, and involved flights between San Diego and Hawaii. As noted below, these issues all occurred on 737-800 aircraft, not the 737MAX-8 associated with the recent Southwest diversions.

The good news is that all flights landed safely, and passengers ultimately got to where they were going. Kudos to Alaska Airlines! This news, however, came as quite a surprise following yesterday’s article about three Southwest Hawaii flight diversions. To have to report on five such diversions in one day is highly unusual.

Were you on any of these three Alaska flights? All diverted within 48 hours over the Pacific.

    1. Monday, August 8, Alaska Flight 806, from Maui to San Diego. It departed at 2:50 PM and had a flight diversion that took place at close to 2 hours in flight towards the west coast. The flight, onboard a Boeing 737-800, returned to Hawaii, landing at Honolulu. at 5:56 PM. The cause of the problem is unknown.
    2. Tuesday, August 9, Alaska Flight 9201, from Honolulu to San Diego. Unbelievably, that flight suffered the same flight diversion fate as their prior fight 806. The Boeing 737-800 departed Honolulu at 9:48 AM and returned to Honolulu just shy of three hours later at 11:31 AM. If you notice the unusual flight number 9201, that appears to normally be used when it’s a special flight created by Alaska.
    3. Wednesday, August 10, Alaska Flight 895 from San Diego to Honolulu. A flight diversion was called en route, and the 737-800 aircraft returned to San Diego at 1:37 PM, just one hour later.

What causes mid-Pacific Hawaii flight diversions?

We hope to learn more about the cause of last week’s flight diversions. The last thing airlines want to do is to divert an aircraft. It is frightening, it is annoying, and it is expensive. Sometimes, however, circumstances beyond anyone’s control can result in an aircraft diverting to a different airport than the one planned.

When a diversion occurs, the airline will either resume the same flight when the causal issue is resolved or will terminate the flight and either create a new flight (AS9201) or move passengers to other flights.

One of the causes of flight diversions is the weather, and we’ve encountered those ourselves. They are rare, however, on flights to Hawaii. As an example, a flight your editors were traveling on from New York to San Jose made a weather-related diversion and ended up in Boise Idaho due to severe summer storms that prevented the flight from operating normally.

Flight diversions for mechanical reasons.

Sometimes things just break or give the appearance of being broken. That takes on special meaning mid-Pacific, over the world’s longest open ocean flights without a diversion point. So if the flight crew suspects a problem, they will immediately diagnose it and make the determination as to whether it is safer to continue or to turn back. When turning back soon after take-off, fuel can be an issue and may need to be dumped.

Flight diversions for medical issues.

Airlines are both very well equipped and trained to deal with mid-air medical emergencies. In addition, airliners heaving invest in telemedicine to provide the highest possible level of medical evaluation. That is an adjunct or replacement to the question of whether there is a doctor or nurse onboard.

Flight diversions caused by passenger disruptions.

When Hawaii airline passengers are unruly or are deemed to pose a threat to the safety of other passengers and crew, diversion may be indicated.

Planning for a diversion.

Since this can happen at any time, you definitely want to fly prepared. Having everything that you need, including for example, prescription medicines, snacks, and whatever else you deem a necessity, can prove to be very important.

We are always glad to be beyond the halfway point to Hawaii since that assures you that a diversion will not occur. We’ve personally been on board and witnessed many a close call for mechanical and medical reasons, but haven’t actually experienced a mid-Pacific flight diversion. Have you?

  1. We where on August 10, Alaska Flight 895 from San Diego to Honolulu. So about 20 mins in, Pilot says we have a small computer glitch we must turn around, Don’t worry. As we get near san diego, he says don’t be alarmed by all the firetrucks on the ground.We land with no issues, Although a lot of cops roll up on the runway, We where in first so they let us off right away, As we got off there was several cops that then rushed the plane. Where all told to wait and they would let us know about a new flight, But don’t ask about the plane they don’t know. They put up a new flight time for 4:30, They told us there are getting a new part for the plane. As that time comes and goes, They change it to 6:30, Then they cancelled never got the truth.

    6
    1. They emailed us later with a new flight that left a day later, That left for SF at 10pm and then a flight from there to HNL 2 days later. I rebooked the min they cancelled on Hawaiian for the next morning. I still need to call and try to get credit for the lost hotel in Hawaii and the one I had to book in SD>

  2. After reading the SWA diversion article, I was the one that reported the 3 Alaska Air diversions in 3 days. I had family on the first 2 flights to San Diego that diverted back to Honolulu. For the first diversion, they were told the freshwater levels on the plane dropped to unacceptable levels. This was the water predominantly used for the restrooms and there are strict health code requirements for that. They never felt in danger for the diversion, but were frustrated by the inconvenience. I never got full clarity on the second diversion, but I believe it was an issue with some interior hardware on the plane, such as a door latch issue. Once again, just frustrated more than anything.

  3. We fly from Honolulu to San Diego on August 10, 2022 at 3:00pm & arrived in San Diego about 11:30pm. Great ✈️ flight! Thanks so Alaska airlines. Nancy & Karsyn

  4. Flight from Sea-Tac to Oahu was diverted 1hour into our flight, apparantly a passengers dog had been improperly placed in the cargo hold.

    7
    1. Yep. Sounds strange doesn’t it? We never got off the plane. Stayed on the ground for an hour and then took off again. It was a small airport.

      2
  5. My family and I were on both of the flights from Hawaii. Very nerve wracking Needless to say my wife may never fly again.

    4
    1. Glad to hear your family and you (and all passengers, crew and craft) are okay as that is always the most important concern.

      If I may ask, might you share what the crew did or any announcements made while y’all were en route? I am curious as to how this was handled while the diversion was in progress…

      Mahalo.

  6. Airlines as a whole are very poorly equipped to deal with medical emergencies. As a practicing anesthesiologist who has come to the aid of passengers on several occasions, I find it appalling that the emergency intravenous fluids and drugs are so inadequately stocked. For example, I assisted a badly sunburned and dehydrated passenger flying from Maui to SF last year. A single 500 cc bag of intravenous fluids was available; 2000 cc at a minimum was necessary. There are medical kits available for around $650 with everything necessary for most emergencies; I see no reason that such a kit is not carried on every commercial flight.

  7. There has also been an increase in solar flair activity lately, which can disrupt radio and other signals and can affect weather.

  8. Awe definitely a scary situation.

    What makes you want to avoid Hawaii in the future.. other than the flight issues?

  9. I was on the flights with my wife and three kids. Each time we took off and returned to Honolulu it felt like we were going to crash.I guarantee everyone on those flights thought about death for the two days we were try to get back to San Diego. For us that was just the start of the nightmare trying to get home. Never going back to Hawaii ever and most definitely would not take Alaska airlines over the Ocean again. No Kudos to Alaska airlines!
    Thank you for listening, still traumatized from such a experience.

    14
    1. Alaska Airlines is a safe and reliable airline. I’m sorry that happened to you but it’s very rare and I guarantee that you were in no danger of crashing

      16
        1. As an aircraft mechanic who takes his job very seriously, yes I can. I can assure you that any aircraft that I, as well as all of my fellow aircraft technicians, work on each and every day are done in accordance with the applicable manuals and a strict adherence to safety. Thus ensuring each aircraft is safe for flight.

          9
  10. Yep, on a direct flight from NY to SFO on a 737. Had to stop in Kansas to refuel. The headwinds had increased fuel consumption… the reason given to us. Made me think how that’s possible with all their calculations for weather and reserve fuel.

    8
  11. Saturday 8-13-22 our flight from Oahu to LAX was routed further North. We came across the Anacapa Islands. The pilot announced the change prior to take off but didn’t mention why

    5
  12. We were an hour into our Alaska San Jose-Lihue flight, and it seemed a bit louder than usual. Turns out they couldn’t close the door completely,and so we diverted back to the mainland.

    4
  13. Booked September flight to celebrate 66th wedding anniversary. Always fly Alaska. Confident the crew will always do the right thing.

    3
  14. Flights 806 and 9201 were both operated by the same aircraft, N564AS, a 737-800. This has me speculating that flight 806 diverted back to HNL due to mechanical, and the next day they decided to ferry the plane without passengers to San Diego (i.e. the special 9xxx flight number), and the mechanical issue wasn’t resolved, leading to another HNL diversion.

    12
    1. If it was a maintenance ferry flight, it would of been flown to either LAX or SEA. While there is maintenance in SAN, they don’t have the resources available at the two Alaska hubs I mentioned above

  15. Same thing happened to me on July 22 but with Hawaiian Airlines. Flight HA57 from San Diego departed and 2 hours later we turned around and landed in LAX. We spent the night in LAX and flew out the next day. They didn’t give much information other than “airplane issues”

    7
    1. The airline should be transparent and let their flying customers know what happened.

  16. My wife & I were on AAL’s red-eye flt from KOA-PHX last Feb 2022. We departed KOA on time @ 10:30 pm +/- aboard an Airbus NEO321. About 2.5 hrs into the crossing the pilot came on the cabin P.A. notifying all passengers “We have a landing gear problem light on in the cock-pit control panel. We have to turn-around & return to HNL” We returned to HNL & arrived @ 3 a.m. HST.
    Of course, @ 3 a.m. there was no arrival gate employees that knew anything about re-routing passengers.
    We ended up with a early morning (8:30 a.m.) flight to LAX, change terminals & planes arriving in PHX at 8 p.m. that evening. A flight that was to take 6 hrs direct to PHX took 22 hrs, KOA-HNL-LAX-PHX. We didn’t receive any rebate from AAL.

    8
  17. Thats really scary to hear. I was on an Alaska airlines flight from San Diego to Lihue on August 8th. Thank God nothing happened on my flight but please keep me posted what did happen on the other flights.

  18. Mahalo for following up on these flight diversions. Haven’t heard anything in the news about them. Three in 48hrs is more than a coincidence. Appreciate your effortss!

  19. Usually when a flight is turned around the airline’s PR department announces the cause: mechanical issue, passenger disruption or illness, etc. since they did not give any reason, Conspiracy Theory me thinks that the pilot or co-pilot had a medical issue. What kind of medical issue, you might ask? Gee, we know that all of the flight crews are vaxxed, otherwise they wouldn’t be employed. And we know that the vaxxes are causing heart issues including myocarditis, strokes, and heart attacks. It sure would be interesting to find out if pilot health was an issue….

    28
    1. “…And we know that the vaxxes are causing heart issues…” I beg your pardon, Rob, but “we” do *not Know*. If you would be so kind, would you please cite your source(s) for this information? Big mahalos.

      1. This is standard anti-vaccination rhetoric. There is no truth in science and the original poster is making an improper inference, rooted in no fact. I would encourage the comment post monitors to delete this series of posts before it starts a myth of bigger proportions. When it comes to Hawaii, the island population deserves only the truth to protect their health, not rumor and innuendo.

        55
        1. It’s the truth. He isn’t lying. He stating a fact. Geez, people. Now then worry about why we aren’t being told the truth. Why is this secret?

          5
        2. Robert L – while I agree the poster is making an unsubstantiated claim, they still have the right to state their opinion. We have to trust that people reading this blog are intelligent and can discern for themselves what the truth is.

          2
      2. See page 12. To me that is proof something is happening.

        1. The “In Memoriam” section”? What it shows is a number of deaths in June, July, and August of 2020, which is before Covid vaccines were available.
          It’s more likely that these deaths were partially due to Covid than to a vaccine that didn’t even exist at that time.

          7
        2. Dee Dee are you talking about the number of pilot and retired pilot deaths in 2020 listed on page 12? Because the vaccine wasn’t out in October 2020 when that magazine article was published

          7
      3. There are plenty of sources available actually – it doesn’t take much effort at all to find these. Start with the CDC VAERS reporting – it’s shocking actually. I wish you well.

        4
    2. Because they couldn’t have a health condition caused by anything else other than the safe covid vaccine right? 🤦

      27
    3. Oooh! You are reaching way out for that one!
      It would be more interesting if it were an auto-erotic misadventure in the cockpit. Rob, get over it brah…

      10
      1. Okay, so I just have to reply to this post Earnly as it made me recall a certain scene in Airplane involving the auto pilot……

        Have a great day!

        2
    4. Not true about all aircrews being vaccinated. A close friend is a Southwest pilot, not vaccinated. That airline, at least, is not making it a requirement.

      2
        1. Not true, my hubby works for Southwest and they were all required to get vaccinated. There are multiple articles from October 2021 where a federal judge blocked the pilot union’s request to block the mandate. Southwest and other airlines are federal contractors and are subject to federal mandates.

          2
  20. Alaska’s number 1 priority is safety. It would be interesting to know what caused these diversions (unruly passenger, mechanical issue, etc). Regardless, it’s good knowing Alaska did, and continues to do the right thing when it comes to the safety of it’s passengers and crew

    19
    1. Alaska does what is required by FAA rules.
      The expression “alaska air does the right thing” is akin to “my car is my friend”

      1
      1. Alaska’s number 1 priority is safety. So yes while they do need to abide by FAA rules and regulations (as do all US airlines) they also put the safety of passengers and crew at the forefront of everything they do

        1
        1. FAA guidelines describe what is safe operation of airlines. You are praising alaska for doing something every airline must do.

          1
        2. While this kind of marketing may reassure some individuals, it is FAA policy imposed upon all operators international and domestic who wish to file a flight plan including USA and it’s territories which compels operators to prioritise human safety as a condition of their certification.
          Alaska Airlines is no different than any other in that regard.
          If I may quote:
          “FAA MISSION
          Our enduring mission is to provide the safest, most efficient aviation system in the world.“

          Just trying to help.

  21. Hello, wondering if the 737- 800 is malfunctioning, it will be interesting to find out the causes of the diversions. Thank you

    2
  22. Pilots themselves have reported that many of them are sick or injured due to the Covid vaccine. Could this be the cause?

    20
    1. This is ridiculous. I’m a pilot and I have yet to work with a single other pilot who has made the claim you’re making.

      79
      1. ummm…Im a commercial airline pilot and Ive been out on medical for a year with heart issues. Problem occurred shortly after second shot. Now you know one.

        17
  23. seems like there all 737 800 ….maybe they need to think about grounding those planes again ….. thank you for the information you guys put out there… mahalo
    julie

    4
    1. The 800s were never grounded as a whole, they’ve been operating since the late 90s with an overall excellent safety record. A couple of airlines have grounded theirs briefly due to maintenance issues that are the result of the airlines trying to cut costs and corners, but not anything to do with the design of the aircraft itself.

      2
  24. We were turned around after 2 hours from Honolulu to San Diego due to, they said a piece of the plane was coming lose, like a door.

    4
  25. Oh and they all just happen to be Boeing 737 Max eight… When will they be permanently grounded globally? Me or my family will never ever fly on one.

    3
    1. No. Re-read the article. They are all Alaskan Airlines 737-800s, not MAX8s. 800s are the “Next Gen” family, not MAX family.

      7
    2. Haven’t heard about any A321s or 330s turning around over the big drink for a while have you? Or 777s?
      (and no, airlines don’t need to disclose reasons for a diversion)

      Thanks Hawaiian Airlines for pulling off in the run up area at OGG to make absolutely certain that we were ready to be over water for 5 hours. I’ll go with Hawaiian or United when I need to get to Hawaii.

      9
      1. Alaska doesn’t fly Airbus over water.. not ETOPS. Alaska is one of the top airlines in safety and on time arrival. The STATs are there. Do the research. I’m sure those passengers were very thankful they turned around and made sure everything was secure and safe instead of pushing through. Put the passengers and their safety first. If someone is having a medical concern turn around don’t keep going. That’s the difference with Alaska.. doing what’s right.

        6
    1. The Boeing 737NG (-800 and -900 series) are very safe and reliable aircraft. Much safer than any of the MAX’s

      1
  26. Going back to the past on diversions, these were rare to hear. But with ETOPS as the standard rule for operating flights between the mainland and Hawaii, even the most minor mechanical items that wouldn’t be an issue on an overland flight will be a big issue on a transpacific route. Being close to the halfway point when these happen causes even more anxiety. But at the end, the rules of what constitutes a turn around and fly back for whatever reason is much more set these days than even during the 707, 747, DC-10 or L-1011 days.

    14
      1. Given that the -800s were built before Boeing outsourced and were built at their Renton, WA facility I’d say it is working out OK. Mayne the fact that they are all Alaskan -800s might have more to do with it given Alaskan’s maintenance issues in the past.

        5
        1. What maintenance issues? If you are talking about flight 261, the issues that contributed to that tragic crash have long been rectified. The aircraft mechanics at Alaska Airlines (as well as all other major airlines) take their jobs very seriously and perform each job per the applicable manuals to ensure every aircraft is ready for safe flight

          1
        2. Nice try do a bit of research they started outsourcing As far back as 2000 with hcl with Rockwell and others and
          and the first 787 rolled out in 2012. They came out of South Carolina.
