I thought the new series was to be in Autumn (Fall)... maybe not then.
Airport is definitely better than Airline. As others have already said, the former is more technical, the latter more personal.
There were a couple of programmes on Hollywood's airport (ie LAX
). I think it might have been a trilogy or even a short series. That was interesting too.
All the Airport and Airline programmes have been repeated several times in the UK, on various channels. Some nights I've had the opportunity to watch an hour of Airline followed immediately by an hour of Airport on a different channel!
I think they've pretty much covered all areas of the airport now. Some more tower visits would be good, maybe baggage handling (I want to know where my bags go!), just more airside ops really.
