I bought an advance from Gatwick Airport to Birmingham, then my flight time got moved later, so I amended the advance to later in the day. I have the amendment ticket coupons; but not the original ticket and am now abroad until to the tickets are needed. So I will be attempting to collect a ticket at noon from the machines at Gatwick when it was meant to be used for journeys from 9am that morning. Is the machine still going to spit it out or will i have problems? Thanks for any help.
