Never flown BA before but it was the best option home from NBO to SFO. I am a little confused on the seat map. BA shows the first seat map so looks like the best remaining seats for a couple would be 13JK. But if I look at Seat Guru for that flight (BA#64 on Aug 27th), it shows a very different configuration that would put the best seats of couples in what looks like the middle, 14EF. So which configuration is correct? TIA.
