From Starbucks in their Happy Hour message for Happy Hour on 12/12/19: Get up to 20% off flights anywhere Alaska flies—Hawai'i, Mexico and coast to coast—when you book travel by 11:59 p.m. (PT) 12/13/19. Visit alaskaair.com/happyhour and use the discount code "IFLYALASKA." Plus another 5% back ($15 max) from Chase.
Was planning a biz trip in early January, fare was a bit on the high side, code made it impossible to resist.
Also compared a couple of BF tickets to Hawaii, subject code came in about $1 less - not enough to go through the hassle of re-ticketing.
