HI there, i would like to ask if anyone knows the air plane ticket prices for the air-shuttle from Barcelona to Madrid and where can they be bought online?

www.iberia.es or any other thing like www.ocioteca.com.

This is a pretty common question - there's a search utility with this software that will find a lot of useful information regarding airlines and trains.

www.studentuniverse.com recently had flights between barcelona and madrid for 51 dollars.
