I was trying to make a booking on Friday and it failed ' Web Socket Error ' BA.com and App both said ... it got as far as the Amex 'SafeKey' verification and I ended up with a pending charge on the card from one of the attempts .. but then it failed and no booking appeared to have been made

Made the booking fine then the next morning .. I'm assuming the pending charge for the failed booking will just evaporate ( if it does turn into a real charge I'll call up , but previous experience suggests it won't )

If the OP had a similar experience to me then it's possible that no booking was made at all , best thing to do I'd suggest would be to call up BA with the flight details and ask do you have a booking for the flights in question ( and if so is it ticketed )
