If you take your kids to the airport, the airline will supervise them to their destination, and if their grandparents are waiting at the other end, I don't really see a problem.

Exactly! The kids are watched every step of the way. It's not like we're popping them on the BART and telling them to fend for themselves. People don't seem to get that, though.

We've seen it, too, and we trust the kids to behave themselves appropriately. They're good travelers. I just wish other people would stop butting in their negative opinions.
