One of the aircraft is a widebody. Identify the routing, the three airlines and the three equipment types.

As for this one, we're down to identifying the 727-200 operator between PHX and TUS. Serious tap in country, me thinks!

11. (1973) From the beaches of the Caribbean to the shores of Lake Louise, you couldn’t be more excited about your upcoming trip from Miami to Calgary. Your first flight out of Miami will make one enroute stop to the connection point where you’ll board a nonstop flight to Calgary. Two dinners will be served enroute and both airlines will be operating the same model of aircraft. Hmm… 1973… Can you recall what two airlines, aircraft type and routing might meet these parameters? Go for it!

Hopefully this tap-in for double bogey won't lip out: #1 the 727-200 PHX-TUS was CO.

As for #11, maybe a pair of 727-200s again:
BN MIA-DAL-DEN
WA DEN-YYC

Go Herb!! Almost a double Eagle! CO is spot on for the 72S PHX-TUS. Here's the overall itinerary:

CP AIR CP 71 Vancouver (YVR) 130p-340p L San Francisco (SFO) 737-200 X6
American AA 580 San Francisco (SFO) 530p-806p D Phoenix (PHX) 747-100 Daily
Continental CO 72 Phoenix (PHX) 910p-940p Tucson (TUS) 727-200 Daily

As for #11, maybe a pair of 727-200s again:
BN MIA-DAL-DEN
WA DEN-YYC

You've nailed the route and the two airlines! However, the aircraft we're looking for is not/was not a 727 of any variant...
