Great deal for flights to/from Washington D.C.
According to Matrix Airfare Search by ITA Software, the fare is priced at $357 for Regular Economy. When you check those dates on United, it may show $257 (Basic Economy) and $357 (Regular Economy).
The $357 fare in Regular Economy permits a standard carry-on and personal item, along with the option for advance seat selection.
United’s $257 fare is categorized as Basic Economy, which does not allow for advance seat assignments; your seat will be randomly assigned at check-in. Additionally, a normal-sized carry-on that doesn’t fit under the seat incurs a $35 fee each way + applicable gate check fees (this fee is waived if you hold a United co-branded credit card or possess United elite status).
