A good sale for nonstop service to/from Seattle

Matrix Airfare Search by ITA Software will price this at $337 (Regular Economy). Use those dates on United should reprice to $237 (Basic Economy) and $337 (Regular Economy).

The $337 is the Regular Economy fare with advance seat assignment and normal size carry-on

United also has a $237 fare but that is a Basic Economy fare. United Basic Economy fares do not allow for any advance seat assignments. Rather, your seat assignment will be randomly assigned during check-in. In addition, normal size carry-on that does not fit under the seat is charged a $35 fee each way + applicable gate check fees (but free if you have a United co-branded credit card or if you have United elite status).
