I have 4 flights booked in the Summer on one booking with BA. I was looking at seat availability on my return flight BA 2166 and the map is blank. All the other flights are fine. I am a bronze card holder so can book for free 7 days in advance. We are flying club World.
My questions are why is the seat map blank on that flight and do you think paying to book seats will be necessary on this busy Summer flight?
We are 4 adults.
