Alaska Airlines + Southwest Airlines: Hawaii Undercover Discounts

Note that this deal has concluded. It still provides an insight into those airfare sales you can expect again soon.

Beat of Hawaii editors recently flew on Southwest Hawaii flights we reviewed and will again be in the air today on Alaska Airlines to the mainland. Look for another upcoming Hawaii flight review soon. Having had a number of positive experiences with both airlines, each of which offers a unique and quality product, we are excited to embark again on another journey across the U.S. from Hawaii. The return will be on an interesting United Airlines Hawaii flight, which we will also share a report on.

In the interim, here’s the return of an invaluable tip we previously shared, which has just resurfaced. One tip provides savings of 14% on Southwest, while the other offer below is a 25% off coupon code savings on Alaska Airlines that is valid today only.
