Great airfare deal to/from Baltimore!
The Matrix Airfare Search by ITA Software indicates a price of $281 for Regular Economy. When booking those same dates on United, you can find fares starting at $181 (Basic Economy) and $281 (Regular Economy).
The $281 fare offers standard amenities such as a normal-sized carry-on and personal item, along with advance seat assignment.
In contrast, United’s $181 fare is a Basic Economy option, which does not permit advance seat assignments. Instead, seats are randomly allocated at check-in. Additionally, a normal-sized carry-on that exceeds the under-seat limit incurs a $35 fee each way + any applicable gate check fees (this fee is waived for holders of a United co-branded credit card or United elite status members).
