I really hope that people are careful not to deviate early, and go as scheduled if the actual fare cost is much higher. Especially with the weather how it's been lately, it takes a lot of stress out of the equation to go as scheduled, especially internationally. Even though it can be a pain going from Memphis. But I've seen flights where they've scheduled people to deadhead out on the last flight of the night, with an hour turn in EWR to go international. Getting you there at the last possible minute. I'm assuming that they just think people will deviate, so why schedule a deadhead with any backups at all?
