Not at FedEx, but flying non rev with a family. For us, we have had some luck finding cheap one ways to get home on. Once we find a cheap flight home, we give ourselves a few days to get to our vacation destination if needed. Price of a last minute hotel or VRBO has to be considered though. I like the VRBO, that way half the family can settle in, if the other half isn’t there yet. Many use a door code that is emailed to you. To me, In the end, it’s worth just buying the tickets if the destination is important. If you don’t mind just looking at loads and going where the wind takes you, non rev can be fun.
