The sale, which ends on Thursday, June 13, at 11:59 p.m. PT, has up to 50% off the base fare on flights across its network, excluding any government taxes and fees. Flights within the continental U.S. can be booked for travel between Aug. 6 and Dec. 18, while flights to Hawaii, Puerto Rico, and international destinations can be booked for travel between Aug. 20 and Dec. 17.
