you tell me? T5 for BA is nice, and econ+ for UA is great, but open to anything. comfort is king (BA econ to USA is horrible!)

have three scheduled LHR-SFO flights in next 3 months, good time to choose a FFP or maybe stick with UA/BA? current UA membership has 6K mi banked. BA blue membership has 60K mi banked (140 tier pts/19 flight segments towards silver)
