It was basically saying make sure you have sufficient credit 72 hours to 24 hours before I fly. That would be they gave me 24 hours notice to make sure I have sufficient credit available, as I always clear my cards, there is no chance any transaction will be declined due to a lack of credit.
My expectation is that if there are sufficient seats, and my payment goes through, my card will alert me to the transaction and then I should be able to check my booking.

I got the same type of email as Crackjack posted, so I was assuming my bid was successful as they would not send me the mail otherwise. The real proof of course is once the payment actually gets triggered and the transaction is confirmed.

Ofcourse if this an email that everyone gets, even if there is no seats available, that would be a great way to upset a lot of customers !
