Thanks for all the suggestions.
By Aviation Week, do you mean Aviation Week and Space Technology? (I would never have thought of looking at that!) That one will cost $99/y or $59 for digital only.
Flight International is $230/y (or I can save $25 by going for digital only). I'll pay it if it's really worth it, but that's kind of steep.
Air Transport World and Airline Business look like they might be a bit too business orientated, rather than flight, and the airliner world site has been down, but I will keep checking. I'm going to look into AOPA as well.
