Useful thread, thanks everyone.
My partner and I are flying LGW-OAK and back on BA2279 and BA2278 in J in a couple of months time. BA's seatmap appears to show the 48J/24W/203Y config.
Appreciating that these planes are subject to regular swap-out, and that all of the CW seats are pretty dated these days, I'm looking for validation of my seat choices! We're currently booked into 2A/2B. Any reason to avoid this pair?
