I just booked a couple of seats in the CW sale to TPA (ex-LGW) on the BA2167/2166 - out 26/12, back 5/1

At seat selection for both flights, I noticed only row 10 backwards was visible, meaning a 4 class configuration. F was not available as I tried to book and it came back with nothing direct, but routing instead through MIA/ORD/JFK (as you would expect)

Looking on KVS...
J9 C9 D9 R9 I9 W9 E9 TC Y9 BL HC KC MC LC VC SC NC QC OC GL
so no F, however, their seatmap shows rows 1,2,3 & 4 but with seats unavailable.

Could F be sold out already? Or might this be just a placeholder for a 4 class config, likely to go to a 3 class at some point in the future? Meaning I need to watch the seat shifters!

Also, I thought I read on here that TPA was going to 7days/week, yet 26/12 has no flight (which it did last year). Just curious.

TIA
