7) HP, YEG to LAS: I'll guess twice a day -- 737-200 -- always stopped in YYC to pick up pax, but not allowed to carry any YEG-YYC.
9) YYC-LAX: DL and AC, both with 727-200
4) part of question missing, but guessing your devious mind, I'll say EUG-Medford (MFR) -- US using the BAC-146. Of course there are about 7 other possible non-stop destinations, so if I'm right, I should get extra credit.
Now back to the game!
