While they're not rock-bottom prices, keep in mind this isn't a budget airline. You’ll get to fly with the top-rated US airline, and won't be wondering why you've gotta pay $15 to wear a jacket, or $25 to go to the bathroom on some "budget" carrier. Those are obviously fake fees -- for now, anyway.
The fare sale, which is valid for travel from May 16 through June 10 and from Sept. 8 through Nov. 11, ends May 31 at 11:59pm CT (or June 1 at 12:59am ET). Note: Some routes may need to be booked 21 days ahead of travel and, of course, seats are subject to availability. Meaning you’ll want to get on this fast to secure your spot.
