United has round-trip flights from Seattle (SEA) to St. Louis, Pittsburgh, New Orleans, or San Antonio (STL, PIT, MSY, SAT) for $157 with a connection. Most flights are in December, January, February, March, April, May, and August. New Orleans flights have a wider range: December to October. Weekends available. Origin/Destination reversible. No Christmas dates available.

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.

Here are some other offers that we think are worth mentioning. List updated 04/21/2026.

We now track coupon codes, discount codes, gift card discounts, and credit card offers that have a better value than their historical averages.
