GoEuro will never charge you for a booking attempt that is unsuccessful. Depending on the stage that your booking fails, you may notice a pending charge in your account, even though you received an error message. This is not a finalised charge and is the result of a pre-authorisation: before securing your tickets from the travel provider, a temporary hold is put on the necessary funds. If the following stage of the booking process is then unsuccessful, this amount is released from our side instantly - it can just take your bank a little while to recognise, which is why it remains temporarily in a pending state within your account.
No action is required on your part to release a pre-authorised amount and generally, depending on the particular process your bank follows, the pre-authorisation will clear after a few hours to a few days. The money released to you by your bank will not appear as credit from GoEuro, since the funds were never withdrawn to begin with.
For some customers, a pre-authorisation looks like a charge in their bank statement - this is because some banks don’t mention if the amount is a real charge or just a pre-authorisation.
If you’re uncertain as to what has happened on your account, we recommend contacting your bank to put your mind at ease.
