Let me tell you a story before you book a domestic flight:
A friend lost a little titanium screw from his glasses. He took the other screw and gave it to a Cuban to find a replacement.
Within a week he got the spare screw delivered. When asked where he got the screw the Cuban answered that a maintenance engineer took it from a Yak engine… (There are three Yaks left in service world wide, two in Cuba and one in FarawayIstan).
Every time I think of booking a domestic flight this story pops up in my mind and I decide to take the bus…
