I just figured that the crew may just smile and know what is up because it seems like from FT quite a few people do it and I'm sure many have had conversations with the FAs and GAs about it. On the international trips they usually switch the crew so it wouldn't happen. I guess as a traveler if I was to do a MR I would want to at least spend a couple days to make the money I spent on airfare worthwhile. If it was not a desirable destination I guess I wouldn't have much a problem just turning around and going right back to where I came from.
