My wife (Gold) and I (EXP) would be flying a US-UK-India-UK-US trip that will be mostly AA flight numbers but we have the choice of AA metal or BA metal on US-UK part. If I understand correctly, the BA metal/service is supposed to be better (not much personal experience, thanks to their YQ, and also because AA had ORD nonstop fpr a few years which trumped all other considerations). However, we are likely to have more privileges with seat selection etc on AA metal. So, my question to those EXPs among you who have the experienced both: How do these two balance out? Are you better off on BA which may be better on the average, or on AA which may be less good on the average but you have better picks among whatever exists? Speaking of that, what are an AA EXP and a companion's seat selection privileges on BA?
