I recently volunteered my seat on an extremely overbooked flight, and was offered a VDB. I asked for certs instead of the VDB. The first agent didn't seem to know how to give certs instead of VDB and asked colleague if they could do that. 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.
