I read somewhere that UA had recently implemented a customer service improvement program to coincide with the roll out of their refurbished long haul fleet, with SFO as the trial airport. On a J RTW in November I found that the two domestic checkins I did at SFO were great with other US checkins being similar, with a noticeable improvement in service. The domestic and international RCCs were very ordinary, but all the RCCs are the same.

The only rather long haul I did - ORD - LHR was good, and on another thread I mentioned that I found the standard of service and food at least as good as NZ, with food probably being better, although compared with both of them, the SQ sectors were a class above.
