That's what I got too.
If there was a problem with the credit card, it would've stopped you before that - for some reason the site didn't accept my credit card, so I had to use a different one... But I got the error message right away.
I'm having the same issues with my credit card. When I first ordered the tickets I could see that the money had been reserved and now that reservation had been removed but there;s n payment on my credit card statement. The ticketing website says that my order has been confirmed.
Same here, the transaction showed up on my online credit card statement yesterday morning. I guess it just took a bit longer to process everything compared to last year. Still nice to know everything is in order so I can start planning the rest of the trip
