Having a problem right now with an ex-US ticket first sector on BA. Booked Thursday night and called BA US first thing Friday to pay. Rep said ticket was showing as 'expired' - as if I had waited more than 3 days to pay. Told her I had booked it the night before and she said she'd rebuild it and email me if there was a problem. No news at COB so called back and another rep said it was in process and should see the charge on my cc (and e-ticket # on checkmytrip.com/ba.com) on Saturday. Got back tonight and none of the above has happened, and Amadeus reservation has completely disappeared.
