I have it and like it a lot. Yes it is true that it doesn't have much airliner stuff though.
My favorite shows are:
Airport: Made by the BBC, 30 minutes long covering real events going on in London Heathrow.
Fasten Your Seatbelt: One hour show discussing different aviation topics for each show, military, general, airliner, and history.
Centennial of Flight: One hour show dedicated to celebrating 100 years of flight covering many aviation milestones throughout aviation's history.
There are a lot of other great shows also. Well worth it, but if you only care about airliners, then you will be disappointed.
The #1 topic is aviation history (both military and civil). Since I am really into aviation history, I like the channel a lot.
