To snag the coveted Companion Pass, travelers must register, book a round-trip or two one-way flights by today (February 20th), and complete their travel by March 31st. Once qualified, they get a pass that’s valid for a future flight between August 7th to October 8th, covering the sweet spot between summer vacations and fall getaways. With flexible booking options, including cash, points, or the new Cash + Points feature, this deal is a solid way to score some savings on a late-season adventure!
