And we're down to the last three...

36. (1986) You’ve just returned to Los Angeles and are looking forward to a few days of R&R back home when you get a call from your department head. Welcome back! Terribly sorry about this Mate, but it seems your technical skills are required to solve a wee problem in Pretoria, South Africa. The Travel Department has found you a great itinerary though - a couple of nonstop flights aboard two different widebodied jets with just a single connection, both on the same airline. You'll not be connecting through Europe and even better, you’ve been booked in Business Class on both flights. Identify the airline, route and both aircraft types involved.
It's not AZ via FCO

38. (1987) Your Tennessee Vols are playing Alabama’s Crimson Tide in a major SEC showdown next weekend. A good buddy of yours has called to say he’s managed to procure a couple of tickets on the 40 yard line. Can you make it? Oh, you betcha! Better yet, if you fly down to Birmingham, he’ll pick you up and drive you back up to Knoxville after the game. As for the flight, this really must be your lucky day. There’s a daily nonstop from Knoxville straight down to Birmingham. Book it Danno! Name the airline and the aircraft please.
It's not UA or a BAe-146. Nor is it DL Connection or a prop of any kind...

40. (1986) Following a productive three days in Abu Dhabi, it’s time to move on to your next assignment in Nairobi, Kenya. There is a once weekly nonstop ABU-NBO flight, but alas, not on the day you need. Thankfully, another airline offers a convenient online connection departing early tomorrow morning and arriving NBO in the early afternoon. The first flight to the connection point makes a single enroute stop, followed by a nonstop into Nairobi. It is the only airline offering an online connection where both flights are aboard vintage four engine jetliners of the same type. As an added bonus, First Class is available on both flights. Airline, routing and equipment please
It's not Saudia, Sudan Airways, Yemenia, Turkish THY, Egyptair, Libyan or Ethiopian, but it is a 707 operated by an African airline. The intermediate stop is in the country of the national airline involved and begins with "B"

I apologize for the delay in responding to your responses over the past three days. The Wi-Fi has failed us again at the park (It is an odd season indeed with everything from to staffing shortages to supply shortages mucking up the works). I will be in Fairbanks through tonight with a good connection from my home.
