IMO, domestic F on AA/US/DL/UA is just all the same homogenized garbage at this point. Poor legroom, poor seat comfort, poor food, poor beverage options (with the exception of liquor), and generally apathetic and uninterested with sometimes flat out rude and disrespectful service.

US domestic premium air travel is an industry that is clearly lacking competition at this point, and the product offerings clearly reflect that. To me, the only airline with an acceptable F product for domestic flights outside of premium transcons at this point is Virgin America.
