Here's a good old fashioned fare war between American and United with big price drops between select cities across the nation. There are some especially good cross-country deals between Washington D.C. and California along with a slew of other routes that rarely go on sale. Fares start as low as $111 roundtrip.

Travel Availability

Rules and restrictions vary by route. Available travel dates are generally scattered throughout the year with the most availability for fall and/or winter travel, excluding peak holidays.

Baggage

These are Basic Economy fares. On American, this includes a carry-on bag plus a small personal item. On United, this only includes one small personal item. A full-size carry-on bag is not allowed on United. A checked bag costs $30 each way on either airline.

Seat Assignments

Seats will be assigned at random upon check-in for these prices. You may pay a fee to choose a seat or choose to upgrade to the standard Economy fare.

Alternate Fares

In general, it should cost $60 more roundtrip for an upgrade to a standard Economy fare. This will include a full-size carry-on bag on United. It will also include advanced seat selection and allow for ticket changes/upgrades on both American and United. A checked bag is the same $30 fee each way.

As an example, I found a flight on American departing Washington DCA on Sunday, September 1, returning from San Diego SAN on Saturday, September 7, for $133 roundtrip.
