This could depend on how strictly you define "single aircraft type", but here goes for a start:

JL 747-200 LAX-HNL-NRT
NH 747-200SR NRT-NGO

2- once again, it appears that I did less-than-fully-complete research; that said, I will attribute this to using Google Maps on my phone, which shows Gifu but not Nagoya


the original destination of record is in fact the closest major airport *with substantial international service* to the park, but is actually the *second* closest "major" airport

as for the remainder of this guess:

• JL is INCORRECT for the first airline
• HNL is CORRECT for the intermediate stop
• NRT is INCORRECT for the connecting point
• NH is INCORRECT for the second airline
• 747 is CORRECT as the aircraft type

Continuing the same one, how about CI LAX-HNL-HND connecting to JL HND-OSA (Itami). Which would be an interesting routing since CI was the only international carrier at HND during this time period, one of many rather bizarre political compromises between Japan, China, and Taiwan.

CI and HND are both INCORRECT
OSA is CORRECT

not too many remaining options for the connecting point

Oh, plenty of options let for the connecting point -- but how many are logical?

Let's go back to my favorite airport-in-the-middle-of-nowhere. I notice you didn't specify that JL is incorrect for the second flight, so...

PA 747 LAX-HNL-GUM
JL 747 GUM-OSA

deductive reasoning for the win

PA is CORRECT
GUM is CORRECT
JL is CORRECT

And just one year later this routing would not have been available. CO had replaced PA on the GUM service, using DC-10s. This was mainline CO, not Air Micronesia, although the DC-10 did run up to Japan and back as an Air Mike service. I think only to NRT, though; OSA et al were served with a 72S (the 72M fleet was all on the truly Micronesia routes). The DC-10 also flew the DPS turn, if I remember correctly -- I'm a little hazy on that one.

Of course, I didn't get to fly on either of those two airlines on my first trip. I was on HK -- South Pacific Island Airways (SPIA) -- on an aging 707 that had served in the Middle East somewhere (as evidenced by the Arabic writing on the No Smoking/Fasten Seat Belts signs). HK lost the government contract with the advent of the 1984-85 fiscal year, but because CO operated the route only 3 days per week I became the very last government contract passenger on 1 October. Fortunately, by then I knew about the $40 space available upgrade to F so I was able to avoid the uncontrolled kids running around the cabin in back. Interesting thing about that particular trip: I was flying OMA-HNL-GUM (USAF didn't have any planes going my way for a few days), and the announced flight time for DFW-HNL and HNL-GUM were both 7 hours 43 minutes. I wasn't kidding when I said Guam was in the middle of nowhere!

Just made a post over on the UA board about SFO discontinuing closely spaced visual approaches and it recalled a fun anecdote.

Anyone on this thread ever land on or depart from SFO's short-lived runway 11/29?

gotta be a story about MAGVAR regression there
