The only time I really consider inflight service a lot is if I'm redeeming a three-cabin F award. Then, I'm likely to try for the best TPAC or TATL product my alliance has.

If I'm flying J, I'm less likely to go out of my way. Might opt for a good foriegn carrier if there's no time-cost to doing so.

If I'm flying Y, I actually prefer the U.S. carrier since that's where my elite status is and I'm not aware of other airlines that will actually put me in a premium/desirable coach seat online at booking time based on my alliance status. In Y, the only things that matter to me are (a) being able to confirm an aisle seat and (b) maximizing seat pitch. What brands of beer are served or what kind of food is served are irrrelevant to me. "Hottie" FA's are irrelevant to me as well.
