Domestic first seating for the transcon route can be regular first class seats (737,757) or international equipment with standard business class (better than first class) seats (757,767). The transcon service is somewhat comparable with transatlantic service but less in quantity and quality.

Check www.seatguru.com for the seats, and search this forum on BusinessFirst (BF) service. In my opinion CO is better than AF (in J).

Enjoy your flight.
