Flights booked using miles aren’t eligible for the discount, and you need to use the promo code LATIN30. Additionally, only economy and basic economy fares are eligible for this discount.

There are some terms you should know before booking:

Note that the cheapest flights from Alaska Airlines are booked as Alaska Airlines Saver fares when you pay cash. This is the airline’s version of basic economy, so you’ll pay extra for checked bags or choosing your preferred seat in advance. Saver fares cannot be changed but are eligible for a 50% flight credit when canceled at least 14 days before departure.

Is It Worth It?

If you were planning on booking a trip with Alaska Airlines or Hawaiian Airlines soon, booking it during this sale could help you save money. The same logic applies to anyone heading to the tropical destinations included in this sale.

It’s worth comparing the fares available with this promotion to those offered by other airlines to see what your real savings are.
