Website doesn't have hidden charges and is straightforward to use. Doesn't get top marks as missed the take-off slot on our recent flight to Prague from Gatwick meaning a 1.5 hour delay but we were kept informed and made up half an hour on the way. Reasonable prices if booked early enough, and the Gatwick departure means overall cost is lower than Stansted departure as London-Gatwick by normal train (not Gatwick Express!) using an Oyster or contactless bank card is much cheaper than the rip-off London-Stansted train.
