San Francisco – Baltimore (and vice versa). $163 (Basic Economy) / $263 (Regular Economy). Roundtrip, including all Taxes – The Flight Deal

Great airfare deals to/from Baltimore!

The Matrix Airfare Search by ITA Software lists prices starting at $263 for Regular Economy. By using United for these dates, you can find fares as low as $163 for Basic Economy and $263 for Regular Economy.

The $263 fare includes a standard carry-on and personal item, along with advance seat selection.

United’s $163 fare is a Basic Economy option. This fare does not permit advance seat assignments; your seat will be randomly assigned at check-in. Additionally, any carry-on that exceeds the under-seat dimensions incurs a $35 fee each way, plus possible gate check fees—unless you hold a United co-branded credit card or have United elite status.
