I fly United almost exclusively and love Channel 9. If it's not on I ask a flight attendant if the captain has "forgotton" to turn it on. Often that's the case. But occasionally a captain doesn't want the passengers to listen.
Chicago is great listening....very busy traffic. You appreciate the job of the ATC staff when you hear them in action. You not only hear your flight but many others on the same frequencies. I enjoy the accents of the many foreign airline pilots flying in, out and across the USA.
It's also the best place to find out the scores of key games when you're flying. ATC always responds to a captain's request for a game update.
