Travel on scattered dates from May through August, excluding peak July travel.
Searching Southwest, I found this price available departing Denver DEN on Thursday, August 22, returning from Austin AUS on Monday, August 25. Perfect for a weekend getaway.
This fare includes a carry-on bag, a personal item, and two free checked bags.
Southwest has an open seating policy, which means there are no assigned seats and you'll get to choose your seat during boarding. The order of boarding is determined by the time of check-in so check-in exactly 24 hours before departure or pay for priority boarding for a better choice of seat.
United, Frontier, and Spirit Airlines all have similar or lower fares, which do not include carry-on or checked bags. Southwest will be cheaper in the end if you bring anything larger than a small backpack. And much cheaper if you need to bring checked bags as well.
