I have been looking to book a couple of flights to France in April. Fortunately I can get on the cheap I deals to TLS which is incredibly convenient. Unfortunately I am not 100% sure on the dates that I can take.

If I were to call up to book they would be able to hold the booking for me for a specified time but they would charge £15. Expedia also have to option to hold a booking. I think this facility would be very useful on ba.com. Does anyone agree or know if there are plans to implement this?
