I've tried to book a ticket with TAP and the payment through payPal didn't go through. I have a booking number that shows a ticket in my name, but no payment made. The email from TAP said to contact the airline to complete the booking within 24 hours. Should I consider this booking closed after 48 hours? In other words, can I ignore this booking now and book other things, or does TAP have a claim on it? Any advice appreciated.
