A few days ago I purchased tickets to Spain on ba.com
I was surprised to find they did not accept Switch, a popular debit card used in the UK, as a form of payment. Most of the low-cost airlines based in Britain already accept this card, along with the usual list of major credit cards, to make bookings on their websites.
Fine, I thought, it's not the end of the world, I'll just use my Visa. So I did. And the transaction was successful. And I received my confirmation email. Good, I thought. Now I can get back to surfing Airliners.Net
Today I got a phone call from BA; the rep told me they were having trouble processing my credit transaction. Hang on, I thought, my credit card was accepted at the time of booking, and I received my confirmation email.....
Anyway, to get to the point, I did not have enough credit left on my card to purchase my ticket. Should have checked this before making the booking, so really, its my fault.
Question: when purchasing tickets, do the merchant's computer systems actually check whether the card has sufficient credit, or do they simply just check that the card is valid?
It just seems odd that you should be able to purchase things online (such as airline tickets) with no credit left.
This isn't a dig at BA (although they could have offered to accept payment with Switch...), just a general query regarding purchasing things online with credit cards.
