United has gone on record to provide lie-flat equipment for all business class configurations from all North American hubs. This apparently only leaves Honolulu based planes in the old configuration.
United has a rather horrible service and catering but an outstanding business class seat (though a bit on the small side) and a great on-demand entertainment system. Given that United is often much cheaper I think this is a winning concept. While I understand it's tricky to re-train a big part of the unionized workforce the catering seems an easy fix.
