Your journey from Aruba to Adak will involve four flights on four airlines. Four different aircraft will be involved. Two of them were built by the same outfit. The other two were built by different manufacturers. You’ll be well fed along the way, too, with meals on every leg. Your first day will involve three flights. Following an overnight layover, you’ll enjoy breakfast the next day while flying nonstop to Adak.

Given the clues provided, this might just be the easiest query of the bunch for a bunch of timetable reading dudes like yourselves. We welcome your thoughts on all of the relevant particulars
We know ALM DC9 AUA-MIA and
RV LEC ANC-ADK

A Northwest DC10 is involved, but MSP is not, so in 1974 it must have been flying SEA-ANC. That leaves getting from MIA to SEA without using an L10, 727, 72S, or any Douglas aircraft (we've already used the two allowed). The 707 was still alive and well, so let's do an American 707 MIA-DFW-SEA.

Northwest's DC10 SEA - ANC is Correct!

As for that one stopper, keep in mind that it could also be the NW DC10, and if that's the case...
