I am not sure what that means, Kathleen. Can you give an alternative description of what happened?
Whenever I have booked with Ryanair or Easyjet you go through all stages before you start giving credit/debit card details. You've already decided whether to select a seat and if so which one. You've already decided whether to add luggage and how much. You've already decided whether to add extras like travel insurance or pre-booked snacks. I agree that if you do add extras, and I do, the flight finishes up much more than the headline price, often double in my case. By the time you get to the payment page, however, you should know exactly what you are going to be charged. The booking is not accepted until you put in the payment details. I cannot see how anybody can get into a situation where they have paid for the flight without knowing how much they are going to pay or how the price could be increased after you enter the payment details?
