Seat reservation tactics - Leaving middle seat empty
We have a lot of flights this year as a family (3 of which are longhaul) and am trying to work out the best seats to reserve in advance in Economy. We are 2 adults, a child and an infant and although we can reserve the bulkhead seats with a basinette, I actually dont like them.
So, the idea was to book, for example, seats A, C and D (in any row), leaving B free (which would be between the child and adult with infant), thinking that its unlikely that anyone would be placed in B unless the flight is full. In which case, the unknown person in B would in most likelihood prefer to switch rather than being stuck between an adult with infant and a child.
I know BA could change our seats, but assuming they dont, do you think this is a good way to increase our chances of getting extra space, which would be used for the lap infant?
