As they do every week, United is matching the previously mentioned domestic sale from Southwest. Frankly, not the most wowing sale from either, but could be of interest to those antsy travelers eager to lock in plans for late summer/fall. Just take into account bag fees. Two free checked bags on Southwest vs. $25 for the first checked bag on United, and $35 for the second bag.
Fares are valid for travel on Mondays through Thursdays, as well as Saturdays, from August 23 through November 2.
Tickets must be booked by May 19.
