American Airlines has round-trip flights from Dallas (DFW) to Denver (DEN) for $97, NONSTOP. Flights April, May, September, October, November, and December. Departures on Monday, Tuesday, Wednesday, Saturday, and Sunday. Origin/Destination reversible.

Note: Carry-on bag is allowed for free on American Airlines. You can avoid paying for seat selection by accepting the randomly assigned seat at the gate.

Note: We often see Spirit and United “deals” for about -$25 cheaper, we usually ignore them since they aren’t priced low enough to be competitive. Keep in mind that those fares on Spirit and United are fee-encumbered and don’t allow for a free carry-on bag.
