Last week flew to LIS and back with Mrs C and Baby C, selected row 2 seats D and F on both sectors via MMB as row one was always greyed out. no problems great flights really enjoyed the seats. Aircraft was an A320 both ways.

Booked another holiday yesterday aircraft is an A319 both ways. Outbound row one is greyed out as usual, so chose 2 D and F again for us all in what shows at the moment as a 3 row CE cabin.

Inbound shows 5 rows of CE, yet the only seats I can select are 3A and C and 4 D and F, the first two rows being greyed out. Tried to select row 3 but MMB won't allow me to choose any other seats. Called BA and got the it's because you're travelling with an infant the rest are unsuitable for travel?

Never heard that before. Any ideas why I can see all other seats but can't select other than two choices in the entire cabin of five rows?

PS I did 4 bottles of monopole!
