There were very cheap deals going on with Cheapoair, where there were round trip flights to Paris for $300 with BA. I bought these tickets a week ago and the costs showed up in "Pending Transactions" as two charges, one for Cheapoair and the other to Westjet. The Cheapoair charge (which was around $50) has already been processed and posted, but the charge to Westjet disappeared from the pending transactions and it's been like this for the last 3-4 days. I called BA and they told me that there was nothing to worry about, that my booking's been confirmed and that the charge will be posted soon enough, but I've read a lot of stories about Cheapoair and I'm worried that the ticket might be cancelled or I'll get charged a lot more than what I originally bought it for. Should I call BA again about this or should I just keep waiting and hope that the charges show up?

Also side question: Why are charges coming up as Westjet when the airline is BA?

Would appreciate any insight on this or if there's another thread about this, please redirect me, thank you in advance!
