I love it ! you can learn so much about whats going on and when big turbulence hits you can hear the pilot talking to ATC's and he doesnt sound bothered at all by whats happening which in turn makes me feel alot better.
My last flight LAX
i listened to Channel nine the entire time........forgot about the IFE. One of the few things i like about UA
and it should be on every airliner.
Sometime in easter 10 .... yet to book :)
