I was trying to purchase extra luggage ... Trying to pay for extra baggage on TAP Air Portugal website, but it comes up with: " We are having difficulty with the credit card details provided. Please validate the credit card information in your profile and try again. (**** - *****)
This was especially frustrating because it says you can purchase it through "Manage Your Booking", yet it not does work.
I want to pay for the extra luggage before I leave for my trip, not to have to wait till I get to the airport and sort it out!!
The problem is not my Credit Card, but TAP Portugal's website.
