PSA: why you should never fly British Airways
They recently introduced a policy whereby you cannot obtain seat assignments ahead of time unless you are prepared to pay an extortionate $30 per leg. Either you cave to their strong-arming, or wait until 24 hours prior to the flight when online check-in, at the risk of being stuck in a middle seat or in non-contiguous seats even if you booked months in advance.
Even by BA’s deplorable standard of service, this is a despicable new low.
