Washington D.C. – San Diego (and vice versa). $197 (Basic Economy) / $297 (Regular Economy). Roundtrip, including all Taxes – The Flight Deal

Discover great fares for travel to and from San Diego.

The Matrix Airfare Search tool by ITA Software lists this flight at $297 for Regular Economy. When checking with United, you may find prices starting at $197 for Basic Economy and matching the $297 for Regular Economy.

The $297 fare is categorized as Regular Economy, which includes advance seat selection and a standard carry-on bag.

United’s $197 fare falls under Basic Economy, meaning no advance seat selection is available. Instead, seats are randomly assigned at check-in. Additionally, carry-on bags that cannot fit under the seat incur a $35 fee each way + potential gate check charges (free if you have a United co-branded credit card or elite status with United).
