First of many guesses.... Monarch Airlines, Boeing 757-200
No doubt that over the years more than a few airlines served this popular destination from London. By mid-1986 however, only one airline did so and alas, it was not Monarch.
Please, guess again, Sir!

I've got an idea that this was not a Spanish airline, so I'll continue guessing... British Caledonian DC-10, being a stop on the way to South America.
You are indeed getting warmer, KT, but didn't B-Cal operate through Las Palmas? In any event, the airline we are looking for here was a former British supplemental carrier. Additionally, we are looking for a different aircraft than the DC-10. I sense success is just around the corner...

5. (1978) Oh No! A big pile-up on I-80 by the Ashby Ave. exit has caused you to miss your United flight out of Oakland to Denver. Worse, it’s United’s only nonstop of the day. It looks like you’re gonna have to drive across the bay to catch one of the many but less convenient flights out of SFO. Not so fast, says your travel agent. There’s another airline offering a nonstop out of OAK to Denver leaving just an hour and a half later. Since you’re booked in Y, you can just have your ticket transferred to the new airline at no extra cost. Right on! Book it, Danno! Identify the airline and aircraft operating this later flight.

Here are some sample questions for you. We'll see if my response time works... As always, even though all of you're smart enough to answer all of these with half your brains tied behind your backs, please address no more than two per day so that all might have a chance to participate.
3. (1986) Based upon schedules posted in the North American version of the OAG, you are poised at the head of the runway at Las Vegas McCarran International Airport, about to take off aboard the longest distance flight heading in an easterly direction (E, ENE or ESE) from LAS. Identify your destination and the airline and aircraft type flying you there.
It is not HP to BOS

11. (1975) After a rejuvenating week in the Caribbean, you’ll be flying from St. Maarten back home to Toronto. There are of course no nonstops but you’ve found an intriguing routing involving three nonstop flights on three separate airlines utilizing three different aircraft types, each built by a different manufacturer. No Canadian airlines are involved, and each aircraft type gets progressively longer. So armed with these clues, can you break down the routing while also identifying the three airlines and aircraft types.

I like it, Toshbaf, but what do I know?! Only what I read in the OAG which in this case indicates that we're looking for a different airline operating an aircraft not from the DC-9 family.
I eagerly anticipate your next guess!

Okay. I'll go with PE to EWR..CO didn't purchase the Newark operation from PE until the following year.
I admire your tenacity, moondog! And, like you, if I hadn't had the benefit of an old OAG from which to research this question, I'd have figured LAS to either JFK or EWR would've been a most plausible answer. And yet, NO! Per the OAG I used to reference this question, there were no nonstops between NYC and LAS - this despite the fact that TWA used to serve JFK-LAS with a 747 or L-1011 through the mid to late seventies. And of course by 1990 America West had restored 747 nonstops between JFK and LAS, a route that by all accounts would appear to be a natural moneymaker. What happened in 1986?
Anyway, we're looking for a different airline operating something other than a 757 on a different - albeit shorter route - than LAS-JFK. And so I shall end with my usual exhortation -
Please, guess again!

There’s no mention of “jet” here, so I’ll offer that the first leg was SXM to Antigua/ANU on a LIAT Hawker Siddeley HS.748 … next would be ANU to Philadelphia/PHL aboard a BWIA 707, and finally an Air Jamaica DC-8-61 PHL-YYZ
Well now, J - you're definitely on to something here with regard to Air Jamaica and its DC-8-61 between PHL and YYZ. Beyond that however, your suppositions veer off into wild and irreverent fantasy. All of the aircraft involved are jets but we're looking for a different routing between SXM and PHL. Smart fellow like you - I expect you'll clear this off on your next guess.

11- "wild and irreverent fantasy" ... that's a great descriptor for some of these flights down Memory Airway
with that being said, I'll offer a more conventional supposition:Eastern with a 727-25 to San Juan/SJU, followed by American with a 707-323 to PHL oops, different manufacturers ... EA L-1011 SJU-PHL makes perfect sense, so who else flew SXM-SJU? was this leg perhaps part of the Air France island-hopper? I'm gonna speculate that the answer is "yes"; the Caravelles were gone by this time, which means the jet was probably a 737-248

Oh, I don't know... they're all factually listed within the pages of various OAGs. As always, I'm more than willing to provide photographic evidence/reference of any and all schedules employed here. As for "wild and irreverent", it sounded good at the time, perhaps because I was feeling wild and irreverent after a couple big glasses of Bulleit Bourbon

See? What'd I say? A smart guy like you would make short work of this one and indeed you have. You are 100% correctamundo, Sir. Here's the itinerary -
Air France AF 350 St. Maarten (SXM) 1000a-1045a San Juan (SJU) 737-200 Daily
Eastern EA 940 San Juan (SJU) 300p-640p Philadelphia L-1011 Daily
Air Jamaica JM 041 Philadelphia (PHL) 835p-950p Toronto (YYZ) DC-8-61 Daily

1. (1975) Ah… the big day is finally here! You’re off to the Bahamas for a week of sun and fun on the beaches up the coast from Nassau. From your home in Milwaukee, you’ll fly on two nonstop flights, each operated with DC-9-30s, with each operated by a different airline. Thankfully you’ll not be connecting through Chicago O’Hare. In perusing all the different nonstops to Nassau from the U.S. mainland, I’ve been able to find only one routing that meets the above specified parameters. Identify the two airlines and the connection point
2. (1986) You need to fly from your home on Vancouver Island to a medical conference hosted by the University of Oregon at Eugene, Oregon. Always up for adventure in air travel, you’ve booked an exciting - well, to you at least - itinerary involving three nonstop flights, each of them operated by a different airline. However, the aircraft type and variant will remain constant aboard all three flights. So then, you know the drill - identify all the particulars related to this question.
We're looking for a jet aircraft here...
3.

Identify your destination and the airline and aircraft type flying you there.
It is not HP to BOS. Nor is it HP to EWR/JFK. 757 is also out
4. (1986) Ah, you do love the convenience of a nonstop flight. For your upcoming trip between London and Tenerife, rather surprisingly only one airline offers nonstop service via a single twice weekly flight departing out of Gatwick. Identify the airline and aircraft involved here.
It's not a Monarch 757. Nor is it a B-Cal DC-10

It's not RW with a D9S nor WA with a 72S. FL 73S and TWA 707 are also excluded
6. (1975) Here’s a softball for the newbies - you’ll be flying from Miami to Los Angeles via three nonstop flights, with each flight operating a different widebody aircraft. Better yet, you’ll be on the same airline all the way through. Based upon what you know of airlines, routes and aircraft deployments back in 1975, please identify the airline, the routing and the three aircraft types - properly matched up with each route.
We know it's Delta operating 747, DC10 and L-1011 aircraft. MIA-ATL-XXX-XXX
7. (1986) You’ve just been informed that you need to fly from Miami to Barbados next Wednesday to pick up a catamaran and sail it back to its owners at Jupiter, Florida. What tha - BeeWee and Pan Am are both sold out between MIA and BGI on that day. A quick call to your travel agent friend reveals a one stop connection involving two nonstop flights - each aboard the same airline with each operating the same aircraft type. Book it, Danno! Identify the airline, the connection point and the aircraft type.
8. (1986) It’s not every day you’d consider flying from Green Bay, Wisconsin to the state capital over in Madison, ya know, but with your truck broken down and a need to be in Madison tonight, you have little choice. You’ve found a surprisingly affordable joint fare involving two nonstop flights, each operated by a different airline but each operating the same aircraft variant on both flights. Please identify all the usual stuff.
12. (1986) Who in their right mind would want to fly nonstop between San Diego and Dallas when one could do so via three nonstop flights aboard three different four engine transports? Would that be you? If so, please identify the three airlines involved, the two connection airports and the three aircraft types.

Another wild guess - Western Airlines, 727-200
I wouldn't say Western's all that wild of a guess, especially given its longtime nonstop service on the SFO-DEN route. However, Western is not the airline we're looking for here and the flight in question was not operated by a 727 of any variant.
In reflecting on the correct answer, I'd say it will definitely feel like a wild guess and you're just the man to correctly make it. Good luck, T

I’ll offer a guess based on a spring 1987 trip, which was DFW-LAS on a noontime DL D8S that turned back to DFW, followed by LAS-SAN on a US 146 that had come in from LAX
remembering we’ve talked about UA with a SAN-LAX-HNL 747, which I believe was a morning departure, the itinerary in question continued on the 146 to LAS and thence the D8S to DFW
