Thanks for the info from everyone who chimed in. I Appreciate it! So, I'm booked in F from PHL to LHR on a 777-200 and then LHR to MIA on a 747-400 (744). I managed to snag 2A/K (wife and I) in the 747 and 2K/3K in the 777. I will report back on each flights/preference, which will occur in late fall. I am hoping that at T-72 I could get the 1A/K for both of us on the 747-400 &777.
