I'm trying to book an avios flight on CX Y. The BA website showed 1 seat remaining for the past week, but I didn't have enough avios.
This morning I received the extra few thousand avios required, so I did a search and it now shows 3 seats remaining. I immediately tried to book it, however, the BA website gives this error: "The flight selected has sold out whilst you have been completing your transaction. Sorry, please try another BA flight." 3 seats are still available when I search again.
What's the flight #/date?
