Thankfully your Québécois tinged Spanish is good enough to have netted you a newly expired OAG from the travel agency located downstairs in your hotel lobby. A thorough perusal of its pages allows you to cobble together an exciting three flight routing up to Montreal involving three different airlines operating three different aircraft types, each built by a different manufacturer. Each of the airlines is also its country’s main flag carrier. As an added bonus, you can complete the entire trip in a single day. Identify the three airlines, the aircraft type each flies and the routing of this trip. Buena suerte!

One more try:
MIA-JFK Pan Am 747
JFK-YMX Aeroflot IL-62

You are edging ever closer, J. Pan Am for the MIA-JFK segment is correct, however the aircraft was not a 747. Aeroflot is incorrect however the aircraft for the JFK-YMX leg was indeed an IL-62.

So then, knowing what you now know, this question should be solved very shortly. Good luck!

And in the FWIW department, my first flight aboard a 747SP came in September 1979 between SFO and LAX aboard Pan Am. The stand-by fare cost me just $13.00
