I have just booked EXT-GCI-JER with BE (#311) on the 2nd November on the DH4.
The total cost, including tax and a £1 card fee, was £32.98. I won't be taking a bag over 10 K.G., so I won't have to pay £2.50 (or £5 at the airport).
BE offers you the option of reserving your seat, so it's for peace-of-mind, particularly if travelling with a family, for £5 each way - or, for more comfort, an extra legroom seat for £15 one-way. Have you taken advantage of either option? If so, did you think it was worth it? Do you have any idea how much revenue is generated by this method?
