It's in F, so it would be minimal delay getting off the plane, but it's a redeye routing and the next flight toward my destination would be about 4 hours later. The delay isn't that big a deal - all I have to do is shop so that my sister can make cookies when she arrives later. Availability is the bigger problem - it got interesting last year when they downgauged my flight from ORD to DTW and they were trying to get something like 14 people to take VDB. I'd probably have to pester UA for ORC to get enough miles to get over the bump to silver if I got rerouted.
