Might I suggest a small reroute which might help your mother with her diet (i.e. being less fed up). Instead of BOS-ORD-SFO, you might try BOS-JFK-SFO which will land you on a 767-200 in a pretty good business class or a 767-300 in a real international business class (or as real as AA get) instead of the MD-80 domestic "First" on BOS-ORD-SFO.
