Skip Thanksgiving with the in-laws and head South of the Border for tacos instead of turkey this November. Book a fall flight from Seattle to Cancun, Mexico for $238 roundtrip on United Airlines.

Travel Availability

As an example, I found seats departing Seattle SEA on Wednesday, November 20, returning from Cancun CUN on Sunday, November 24, 2019. Perfect for the Thanksgiving holiday stretch.

Other dates are also available for daily travel between November 16 through December 16, 2019. Some scattered seat availability can be found in August and early September. For you last-minute travelers there are also some departures at this price leaving as soon as today.

Baggage

This Basic Economy fare only includes one small personal item. A full-size carry-on bag is not allowed. Checked bag fees start at $30 each way.

Seat Assignments

Seats will be assigned at random upon check-in for this price. You may pay a fee to choose specific seats.

Alternate Fares

United's standard Economy fare is a whopping $456 more, or $694 roundtrip, for these dates. This includes a full-size carry-on bag, standard advanced seat selection, and allows ticket changes/upgrades for a fee. First checked bag fee is the same $30 each way.

Since the upgrade is substantially higher on this route, I would suggest just paying for a checked bag on the Basic Economy fare if you're unable to travel with only a personal item.
