I was being so careful checking everything reading everything and at the end of the booking process it told me to make sure all details were correct. I then clicked back but had to fill in the details again and I then took the process right through to the end and completed the booking. I then received 2 emails and I realised that the booking had gone through on the first occasion as well.
I telephoned them immediately on a very expensive call line. They told me that they could not cancel the booking and after some debate they said I could but would have to pay a £35 admin. fee.
I wrote to them but they insisted that I must either pay the full price for the flights but they would offer the discretionary refund by paying the £35.
I had no alternative other than to pay the fee. I have not been on their web site recently but when I booked some Flybe flights it told you not to touch or click on to anything until the process was complete. Obviously clicking could activate a double booking.
I learned from my mistake and will never do the same again but I think £35 is a high fee to pay for such a simple error. I hope that Jet2 also warn their passengers in a similar way.
I had a problem when I booked some flights back in August. I have flown with Jet2 previously Leeds/Bradford to Belfast and this time it was to Barcelona.
