Today Only! 50% Off Alaska Base Fares With Promo Code: Cross-Country Flights Starting at $113 Roundtrip, $57 One-way

Today only Alaska Airlines is running its Fly One, Get One Valentine's Day sale, and in honor of the holiday the carrier is marking down many of its cross-country base fares in half! So be the first for takeoff in your Valentine’s heart with an impromptu romantic getaway.

Discounts will only reflect on the base fare of the tickets so you'll remain on the hook (or Cupid's arrow) for the taxes on these flights, but you'll still see some amazing price drops. All you need to do is enter promo code: COAST2COAST on Alaska's website when searching between the two applicable transcontinental city pairs, and you'll start to see the savings!

Promo fares are noted with a little squiggly looking "e" symbol, and although the sale language leads you to believe you'll need to purchase two companion tickets, we've found that they work on a single roundtrip itinerary and even on one-way tickets. The promo code is valid on select routes but for any daily flight starting as soon as today through March 14, 2019. While the month travel window is a bit last-minute, you can grab some lovely deals if you're looking for an impromptu getaway with a loved one.

Act fast! The promo code COAST2COAST is set to expire at midnight tonight ET, February 14, 2019.
