One trip with a connection:

Continental (DEN-IAH-LGW)
Northwest (LGW-MSP-DEN)

Just one:
KLM, MAD-AMS, 738

Alaska - SAN-SEA (737-700 N609AS)
JetBlue - JFK-LAX (spectacular flight on a Mint "throne" in 2015 - A321 N943JT)
Korean Air - LAX-GRU (77W - HL8217 - first time eating a bibimbap - it made me addicted to Korean food)

If I Recall Correctly...I flew National Airlines exactly once. The year was 1972, and my father (a contractor for NASA) was making a business trip to the Cape and took me along (I would have been nine years old). Flight was IAH-ORL, nonstop 727. For the return flight we took Eastern, but I believe I had a couple more trips on Eastern before it folded.

Memory, memory...This trip couldn't have been 1972, because in 1972 we took a driving trip to visit my grandmother in Ocala. This trip must have been 1970 or possibly even 1969; I suspect 1970 because I believe the trip was taken in conjunction with the redesigns in the aftermath of the Apollo 13 incident. I stayed with grandma while Dad was at the Cape. And I felt sure that it was out of the old Orlando airport (now Orlando Executive) because I still recognized the terminal profile when I saw it in 1983 as a Navy man assigned to the nearby Nuclear Power School, but according to Wikipedia (which we all know is never wrong) Eastern had moved from ORL to MCO before 1968. We may well have flown into MCO (as a joint use facility) on National, but I'm still inclined to think that we flew out of ORL on Eastern. I do remember a very temporary-type terminal waiting area, though, like a big tin shed. Of course, it was more than fifty years ago....

Vietnam Airlines, and the flight wasn't even from or to an airport in Vietnam. In December 2011 I flew from Vientian in Laos, to Phnom Penh in Cambodia. I was a bit surprised to see VN fly this route, but it turns out it was part of a multi-segment flight: HAN - VTE - PNH - SGN

Could be some from when I was younger (pre-2000) I can't remember but I think this is the list. I also lumped in regionals with the major.

Virgin Australia Regional - I wanted to fly their Fokker 100s before they're retired so I booked a return trip from Perth to Broome, with a VARA Fokker each way.

Flight up there was cancelled and I was moved to a later flight on a mainland 737. The return flight to date is my only trip with Virgin Regional and it was awesome.

Hi,

I guess maybe not that mainline but thinking back I maybe only flew one airline just once. Too much customer loyalty and low-cost roundtrips or charter breaks maybe.

But I remember in 1996 whilst trying to do my "Gap" year placement (in the South Pacific...) I had to take a very early morning flight from Suva to Nadi in Fiji. I'm not sure but I think the airline was called maybe Air Fiji and the plane was most likely a smallish twin turboprop in a white paintscheme with a bird maybe in the logo.

I generally just remember being tired but also really excited as was off to my country of placement (Vanuatu). But also a little lonely as was off on my own whilst my new-found friends/fellow schemers were mostly staying in Fiji.

But it was a nice and short early flight and as for the cost I think the organization just payed since they didn't want me missing my connection. Probably the only "company" flight I took in my whole life(!)

Anyway sorry for going on and on a bit but hope it might have proved useful/interesting and many thanks again,

Ps762

I fly only when traveling with my family. I only "specially" include a new airline if that does not hurt financially. Still, a decent list has developed with Motor Sich An140 as the highlight

Aerosur 722 LPB-SRE (old)
Air Nostrum A76 MAD-BJZ
Vueling 20N SVQ-BCN
Ryanair 738 WMI-LPL

Alitalia 320 FCO-TRS
Norwegian 738 VNO-ARN
SAS 738 ARN-FRA
Avion Express 320 WAW-MAD (sadly replacing LOT's 734 which I was dreaming about)
StarPeru 732 TPP-LIM
Cimber CR1 VNO-CPH
Tiara Shorts 360 BON-AUA
Citilink 320 CGK-SUB (may not count because I have 8 more flights with Garuda)
Batik 320 UPG-AMQ (may not count as I have 22 flights on LionAir + Wings)
Merpati Xian MA60 DPS-LBJ
TAM 320 REC-FOR
Motor Sich An140 LWI-IEV
Windrose A76 KBP-IFO
Tiger 320 HBA-MEL (so disgusting. the only airline I would never ever fly again)
Vietnam 321 SGN-VDH
Indigo 320 CCU-JAI
Interjet 320 MEX-TGZ (was dreaming of an SSJ; alas...)
Aeromar A76 PXM-MEX
Myanmar National E190 RGN-HEH
Pacific Blue 738 AKL-TBU (does not count if we deem it to be part of Virgin Blue)

33 in total. when I started counting, I expected to get somewhere between 5 and 10 only...

Only one. North Central. MKE-ORD.

Buta GYD-TBS
Turkmenistan ASB-MYP
Myanma RGN-NYU

Thai HKT-BKK
Aero California MZT-TIJ
Air Seychelles SEZ-AUH *EY metal, operated HM crew

Technically, both on SAS!
SAS: UME-ARN
SAS Ireland: LHR-ARN

There's also Merpati/MZ, BDO-HLP, around 15 minutes gate to gate. It's not my only time flying with them, but it was my first time where I can remember it. My parents told me that the last time I flew with them, I was just several months old. So maybe it counts?

Mandarin Airlines MZG-TSA E-190
Republic Airlines DCA-PHL E-175
SAS OSL-TOS 737-700
Shuttle America YOW-ORD E-170

A couple of edge cases:
Austrian Airlines FRA-VIE MD-87 - I later flew Austrian SOF-VIE-ORD, but that time it was Austrian Airlines operated by Tyrolean Airways
Continental Airlines HNL-SFO 767-400 - It ended up being the very same day that Continental and United got their post-merger single operating certificate

Just one:
America West

Shockingly, only flew them once, one-way, when I was a kid. Never rode them again until well after the US/HP merger was complete. Still seems like AA PHX is very much the HP mafia.
