Earlier this year, we did exactly what Southwest asked during its free companion pass promotion. We registered, flew one qualifying round-trip, and earned the promo Companion Pass, good for months. It was easy, just like the pitch, and we wrote it up at the time and meant the praise.
Then we went to use it and hit our own misreading of terms that were, in fairness, perfectly clear. Southwest spells it out: you book your travel now, and starting August 10, 2026, you add your Companion to the existing reservation, with until October 7 to fly.
We read that in a hurry and assumed we could book the pair together now. You cannot. You buy your own seat first, and the Companion goes on afterward, starting August 10, once the window opens. It is an easy thing to misjudge the first time you use one of these, and it is exactly where the trap sits.
We were booking a round-trip from Lihue to Kahului on August 16, and Southwest showed a fare of $530 for two. If you book now to lock in a good fare and your own seat, you’re gambling that a seat will still be open to add a companion once the window opens on August 10. If you wait until the 10th to book both together, you’ll know two seats exist, and you’ll buy whatever the fare has climbed to by then, which can run past what two seats booked early would have cost.
Move early, and you risk the availability. Move late, and you risk the fare. Either way, the free companion carries risk, and that is the fence. The pass we earned would have made Southwest the cheapest seat anywhere, our companion flying for taxes alone, but we could not lock the companion in beside us until the 10th.
Choosing interisland seats that close in, now that Southwest assigns them, is how couples end up split across the cabin or stuck in middles. So we took the bird in hand.
Hawaiian had the same Lihue-to-Kahului round trip, with seats confirmed, for about $100 less than Southwest’s $530, so we booked it and moved on.
We are not against these deals. We chase them, earn them, and use them when they fit. Every one of them asks for the same thing first, and it is not really money. It is flexibility.
Southwest’s free companion seat has a timing fence.
Southwest’s Companion Pass is the cleanest pitch in the group. Your companion can fly with you without paying an airline fare, though taxes and fees still apply, starting at $5.60 each way. For Hawaii travelers, that can be a strong savings when the timing lines up.
The promo version, the one we earned, hides its fence in the redemption. You qualify first, then wait for the pass to activate, and until then, the companion booking stays out of reach.
The full Companion Pass has a different fence. It takes 135,000 qualifying points or 100 qualifying one-way flights in a calendar year. That is attainable for some frequent travelers and card users, but it is not casual.
There is also the bag change. Southwest’s old “bags fly free” promise ended in 2025, though cardholders and some higher-fare tiers still retain checked-bag benefits. That changes the old easy math around what the trip really costs.
Alaska and Hawaiian’s $99 fare still works, but asks more.
The Alaska and Hawaiian Atmos $99 Companion Fare is the one we would not dismiss. For many Hawaii travelers, it can still save real money, and even the card-review crowd rates it near the top. The primary passenger pays the full fare, and the companion fare is $99 plus taxes and fees, starting around $23.
That can be a strong deal on expensive Hawaii routes. It also keeps asking more than it used to.
The renewal version now requires $6,000 in annual card spend, which many travelers once took for granted. As of July 2025, it no longer works on multi-city or open-jaw routes. And the primary ticket must be a paid cash fare, so you cannot apply points or award travel to it.
Each of those changes the feel of the offer. The fare can still pay off, but only if you keep the card active enough to hit $6,000, keep your itinerary simple, and pay the primary seat in cash.
The $99 fare can be good and still be a trap. The trap is not that it never delivers. The trap is what you agree to do before it happens.
Hawaiian’s card discount fades after the headline.
The Hawaiian Airlines World Elite Mastercard is a different case. Its companion benefit is not a companion pass, even though some coverage blurs that distinction.
The card has a $99 annual fee. The headline benefit is a one-time 50% companion discount on round-trip coach travel between Hawaii and North America, usable during the first 13 months. After the first anniversary, the ongoing benefit becomes a $100 companion discount each year.
The offer you notice is the one-time 50% off. The offer you renew every year after is $100 off.
For some travelers, that may still be fine. If you already want the card, already fly Hawaiian or Alaska, and already have a qualifying trip in mind, the discount can work. But it is not a continuing half-price companion ticket.
The sites cheering these deals have their own fence.
Many of the sites praising these cards disclose it themselves. They may earn compensation when a reader clicks a link, is approved, or opens an account. That is a normal business model, not a scandal, but it points the writer in a direction, toward the reader who signs, and the disclosures are worth reading closely for exactly that reason. Those sites get paid when a reader moves toward the card. We do not, whether you apply, ignore them, or cancel.
The value in these offers is usually real enough to advertise and fenced enough that plenty of travelers underuse it or forget it. The people cheering loudest are paid at the moment you sign, not the moment you find the fence.
The twofer is not a gift.
We still use the good ones when they earn their keep, the Southwest promo pass when the timing lines up, the Alaska and Hawaiian $99 fare when the fare math works. We would not turn down the Hawaiian card discount on a trip we were already taking anyway. None of that is the point.
The point is what it takes to win. If the travelers who like these deals have to think this hard, plan this far, and bend this much to come out ahead, the twofer is not a gift. It is a contract, and the house is holding the pen.
Which of these have you actually pulled off, and did it turn out to be worth what you gave up to get it?
