A word of caution when booking,
BA/Comair and Kulula codeshare flights so if you see a 4 digit
BA number you will be on Kulula metal, which could be a 738NG less than 6 months old and buy on board such as I flew a couple of weeks ago. Conversely, a 4 digit
MN flight number is
BA metal which means complimentary drinks and meals as appropriate.
Kulula aircraft are all economy.
Sorry I can't help with seat plans though

After Monday and Tuesday even the calendar says WTF...
