Photography final project, I need music that has to do with traveling, can you help?

For my photography final, we're supposed to do a photo story compilation with 30 pictures of an event that took place in our lives this year. I am doing my trip to Europe. I have pictures to include from the plane, airports, Madrid, Spain and Paris, France... can you think of any songs, any genre at all that have to do with travel?

I'm just looking for a general idea, we have to set the project to music, and I actually need a bunch of songs because of copyright law our teacher will only let us use 10% of any song... so on an average song thats like a 30 second clip.

"I'm leaving on a jet plane, don't know when I'll be back again"

It's by John Denver, it's called "Leaving on a jet plane"
Also, Peter Paul & Mary

The theme from the old television program here in the states, "Route 66" or "Back in the USSR" Beatles and others
