Hi all: Now that AA has really stepped up its LAX-LHR codeshare flights on BA metal with 100% miles etc., it's very tempting to get on these planes. The cabins are in better shape than the AA 777s and it's a nicer comparative service in all cabins. However - I continue to fly AA metal (flights 135 and 136) because as an EXP I am very likely to get an upgrade on my economy ticket to AA business using an eVIP. Question: Is there ANY way to get an upgrade to BA business (Club World) on one of these AA code share flights using AA EXP status/eVIP's/miles? I get different answers on this. Once when I was checking in at LAX, they "upgraded" me to premium economy, but I got the sense that that was just because the ground staff was needing to free up some room in the back and they were on the lookout for status holders to move around. But Premium Economy sure isn't Club World. Love to get some feedback on this - thank you!
