Delta and United have round-trip flights from Dallas (DFW) to West Yellowstone (WYS) for $314 with a connection. Flights August to September. No Thursday departures. Very few weekends available.

Delta allows one carry-on bag and one personal item for free. You can avoid paying for seat selection by accepting the randomly assigned seat at the gate.

If you travel on Delta often, consider getting their credit card. Most of their cards allow for a free checked bag perk and a 15% discount on points redemptions.

United’s “Basic Economy” fares do not allow for a free carry-on bag. Only a personal item (like a small laptop bag) is free. Seats are randomly assigned for free prior to boarding.

The personal item size on United is smaller (9 x 10 x 17 inches) than Frontier or Spirit (8 x 13 x 18 inches).

If you use the United℠ Explorer Card, your first standard checked-bag for you and your companion is free, you get priority boarding, two United Club passes per year, and you get a 25% discount on inflight purchases on United-operated flights as a statement credit.

You can usually save more money by booking your flight+hotel together as a package instead of separately.
