My next guess is North Central.

Correct. My source is airline historian David Stringer's article about the history of North Central in the June 2016 edition of Airways Magazine

28. It’s a dreary autumn afternoon in Kansas City with snow and sleet forecast for the weekend. There’s a knock at the door. Gasp! It’s the Western Union man with a telegraph from your cousin Arnie. You are cordially invited to join him and Ginger, his newfound bride to be as they tie the knot this weekend in Las Vegas. Ginger! I thought he was going out with – oh never mind. Vegas sounds great right about now. You can rent a tux when you get there. There are no nonstop flights but there is a two-stopper that departs MKC at 8:20am, arriving Vegas at 11:28am. Yeah, but does it go through Denver? That’s where the storm is right now, so you don’t want to go through there. Good news! It doesn’t. And better yet, First Class is available! Identify the airline, the equipment and the two enroute stops.

Frontier via DAL and ABQ, on a 737-291.

Correct! Here's the schedule:

FL 41 Kansas City (MKC) 820a – 938a B Dallas (DAL) 1015a – 1049a Albuquerque (ABQ) 1110a – 1128 L Las Vegas (LAS) 73S Daily

32. There are two daily nonstop flights between Seattle (SEA) and Dallas (DAL) One of them is operated with a pure jet, while the other features a fanjet powered aircraft. Identify each aircraft and the airline that operates it.

The pure jet would be a Braniff 720. The fan jet would be a Continental 727-200.

Close enough since if I were to tell you that Continental is the other airline, it would be an easy progression to then move to CO's 720B as the fanjet of record.

AA, BN, LR, MO & QB identified so far. Aloha, Lanica and TACA subject to further review

And this clarification engenders a couple of bonus quiz items, of course.....

#1: What was the first specific jet aircraft type operated by First Air and what year did the air carrier introduce this type? ANSWERED

#2: The airline operated the Hawker Siddeley HS 748 for a quarter of a century. What was the year when First Air finally retired the last HS 748 from their fleet?

Permit me to throw Aviateca into the mix as I know they were operating the stretched series 500 One-Eleven into MSY in 1971....but I'm not sure about 1970. As for Lanica and TACA, I'd take a look at both MIA and MSY in your OAG. And I'd take a peek at SJU as well as LIAT operated the One-Eleven into that airport at one point....but again, I'm unsure when.

LIAT's the one I'd originally identified that you were missing. As for the others - I'll check but considering the short distance between Central American countries and MIA/MSY/IAH, if any of those airlines' flights originated from Central America, they would not be displayed in the North American OAG. Aviateca used to come in out of Merida, so that's a possibility that I'm pretty sure I checked. In any event, I'll double check all of 'em tonight!

29. Only one airline within the pages of this OAG offers flights aboard a turboprop airliner with both First and Economy Class seating. Identify the airline and the aircraft.

The question here might well be: when did Air Canada cease operating the Vickers Vanguard? I believe their Vanguard aircraft were configured with an F/Y cabin and I also think AC was still operating the type early in 1970. So in any case I'll go with Air Canada and the Vanguard.

And you would be correct, Sir! Air Canada's Vanguards saw a lot of action in the Maritimes - I'm curious now how far west they operated in late 1970. I'll get back with ya on that, eh -

So how was your Dornier 328JET flight, buddy?

I was impressed. The cabin feels surprisingly spacious for a small regional jet and the inflight cabin ambiance is not overly noisy despite the engines hanging just a few feet outside the forward third of the fuselage. Denver Air Connection provided an affordable and gracious service making this a most pleasant flight indeed.

The CAB awarded Frontier DAL-ABQ-LAS in 1969. However, Frontier was not able to compete against CO and Texas International between DAL and ABQ, or TWA between ABQ and LAS. Frontier suspended the route in 1971, and operated it only intermittently afterward.

1. In 1973, Frontier agreed to give this route to another airline. Which airline did they agree to give it to? Continental would be my guess based upon an earlier question and answer...

2. What two routes of the other airline would have been given to Frontier in exchange for this route?
Many of Frontier's services from Oklahoma/Kansas were inherited in the Central Airlines acquisition. These were multi-stop routes. Possibly Frontier picked up nonstop Denver to Wichita and Oklahoma City service?

The route exchange was not approved by the CAB, and the route disappeared from Frontier's route maps by 1978.

And here's a hint: #1 - This was not a new aircraft but had seen service with other air carriers as the type was no longer in serial production.

I'm thinking along the lines of the Fokker F.28 or the BAC-111. Let's go with the Fokker - a common sight around Canadian skies for many years... Second choice the BAC

As to question 2, it wasn't that long ago. I remember seeing the 748s in the schedules up to The Pas and Churchill I think as late as 2005 when I went up there. Wild guess - ten years ago, 2008.
