Identify each airline, the aircraft type, the connection point and three intermediate stops made by each flight.
I’m 99.9% certain that the only airline serving LRD was Texas International, and their fleet consisted of the DC-9-10 and -30. Coincidentally, those jets were also the mainstays of Hughes Airwest, which would therefore have been the connecting carrier into PDX. To the best of my recollection, the only point where one might have been able to connect from TI to RW was Salt Lake City/SLC.
With that, let’s try TI LRD-SLC via- Austin/AUS
- Dallas/DFW
- Denver/DEN
Followed by RW SLC-PDX via- Pocatello/PIH
- Twin Falls/TWF
- Boise/BOI
I also have to think that multi-stop routes such as these were more the province of the -10
Very well thought out and presented, J 
. And - you're off to a good start on the airlines and the initial routing. Texas International and Hughes Airwest are indeed the two airlines of record, while Austin and Dallas are the first two stops on the TI flight. Beyond that though, we'll need to consider alternate routings and a connection point that is neither DEN nor SLC. As a result, you'll have to start all over with your Hughes Airwest routing. Thinking about the route networks of TI and RW, I'm confident a wily old OAG reader such as yourself will solve this one sooner than later.
13- well, the first step toward a correct answer is to acknowledge that I actually presented
two-stop flights rather than the requisite three ... that being said, the routing for the TI flight becomes obvious as the third stop was Albuquerque/ABQ and the connection point was Los Angeles/LAX
so as for RW, there are numerous possibilities for LAX-XXX-YYY-ZZZ-PDX; let's start with San Jose/SJC, Sacramento/SMF, and Klamath Falls/LMT
I’ll give you “wily”; not so sure about “old” in a mental/attitudinal context, although in a chronological one I can’t actually argue *too* much
as for “OAG reader” … I spent *way* too many hours during my college years poring over the OAGs, and have used those on
departedflights.com to develop some of the questions I’ve posted in the thread …
