The second agent informed me they only give certs for double the amount paid for the original ticket. I was on a cheap MR fare, so I went with the VDB. I'm just wondering whether the agent didn't want to offer me the $ certs and was feeding me a line, or whether this is actual policy?
Insight appreciated.
