I had two award tickets rather than an ECV departing MSY on Sept. 2.

The CSR put the miles back in my account while I waited on the phone. She said it would take 1-2 billing cycles for the taxes to be posted back to my credit card but, in reality, this money has already been returned to my credit card account and I can see the credit there when I log in online.

So my experience would lead me to expect quick and courteous action. However, there could be procedural reasons I don't know about, which could cause it to take longer for the ECV to post than for a credit card refund or miles refund?
