What's the longest you've ever flown non-stop?

This February, Seattle to Singapore nonstop - which would be slightly under 16 hours, but we sat on the tarmac for an hour and a half before takeoff, so I’m counting it. Especially as I was in coach. And was flying on to New Delhi from Singapore a few hours later.

I’ve also done a few other 12+ hours over the Pacific. The Pacific Ocean is really, really big.

I don’t miss flying (I don’t get the people who are taking airplane rides to nowhere. To me, the airplane ride is part of the price of being somewhere else.) I do miss being somewhere else for a short time.

15 hrs Doha Houston
Pretty empty flight so got three seats to myself and the flight attendents were generous with the wine so plenty of snoozing.

When I flew back from Heathrow to JFK after 12 days in Israel, I was seated at the end of a five seat row. Apparently, a family of four had the other four seats, and they didn’t show up. The flight wasn’t full, so the airline didn’t need to move people around to give people more room, and I ended up with the whole row to myself. I’m not even that tall. I put up armrests to sleep lying down on the seats, but I only actually took up three seats. What was nice was taking all my stuff down from the overhead and using the understowage of the empty seats, so I didn’t need to keep getting up to get stuff, or just doing without, because I didn’t want to block the row.

Someone sitting on the other side of the five seats, in a pair of two, asked if I minded if she used the seat at the end of the row for her stuff. I told her I didn’t own the row; it was just my good luck that a bunch of people didn’t show up.

I should have bought a lottery ticket that day.

Oh, yeah-- it was British Airways, and they automatically bring you a glass of champagne when you board (maybe only in Comfort+ and 1st class, but they brought me one). I don’t normally drink, but this seemed like a sign, so I drank it. When you haven’t had a drink in a few years, a glass of champagne hits pretty hard, and I’m a tough insomniac. So the fact that I slept immediately for about 90 minutes was worth a parade, if anyone had offered.

Chicago to Mumbai was just shy of 20 hours.

New Delhi to Chicago was about 15 hours.

Chicago to Dubai was 13.5 but the return trip was 15.5 hours.

A direct flight from Hawaii to Toronto. I think it was just under nine hours.

Modhat on, This is an official warning.

No need to be insulting to other posters. If you really must, take it to the pit in the future.

H’m. I was doing longest single leg. My longest full trips were Melbourne to Orlando; between layovers and intermediate flights, maybe 24-30 hours. It’s been a while since I’ve had any reason to do so, so I don’t recall precisely.
I live a couple hours from the nearest international airport. We’ll usually get a room down in Melbourne the night before, especially if the flight leaves in the morning. I’ll often get a room at the destination airport as well, just to get some sleep before driving on to the final destination wherever. For example, the next trip to the States will probably be Melbourne-Brisbane-Chicago, then pick up a car and drive to south-central Michigan. As the duration for the flights is a bit over twenty hours, including layover, I think you’ll agree a nap in Chicago would be a good idea…
Most of these trips have been coach; business is just too expensive for the long leg. I’ve only once taken one leg from US to Aus in business, using points. Coach is bearable, but I agree business is much better.

Back in my oilfield days, I made a bunch of trips in the 10-12 hour range. Longest non-stop that I recall was Amsterdam - Johannesburg on KLM, about 11 hours. That was one of the extremely rare times I got bumped up to Biz class, so that was a score.

Longest with stops was Houston-Frankfurt-Dubai-Abu Dhabi, on Lufthansa in coach; 18 hours in the air plus about four on the ground. I was barely functional on arrival.

Most tortuous was Paris-Luanda, on TAAG Angolan’s one ancient 707. Scheduled for about nine hours, the plane had a mechanical fault somewhere over north Africa that somehow required backtracking all the way to Lisbon, arriving in the middle of the night. We sat under armed guard in the deserted terminal for about three hours, then were bundled aboard and successfully attained our destination late that afternoon. So roughly fifteen hours in the air. Oh, and no meal service the entire time, neither on the plane or during our forced layover.

Oh, well, better than a month on a heaving wooden sailing ship, I guess.

Boring here. Never having flown anywhere but domestic (US) flights. We’re east-coasters - so a few flights to California on the order of 5-6 hours.

If I count the time I went to Hawaii, it’d add up to about 12 hours (plus layover time).

LA to Sydney for me, too. And I’ve done Auckland - Fiji - LA - London as a single itinerary, but with a two-night stopover in Fiji and a one-night one in LA, so that wasn’t so bad.

I really want to go back to Australia (if they ever let Americans in again), but the process of getting there is daunting.

13 hours flight time between Toronto and Beijing. Unfortunately we were diverted from Beijing to a nearby “domestic” airport due to weather. Because there were no customs and immigration at that airport we couldn’t deplane. So we just sat on the tarmac for 15 hours until a replacement crew was bused in from Beijing. Then we flew to Beijing, where there was a huge backup at gates and we spent 3 hours on the tarmac.

All told we were on the plane for 30 hours.

Later we found that the airport we had been diverted did indeed have customs and immigration facilities. Either the airline or the authorities didn’t want to deplane 400 passengers there for some reason.

Semi-off-tipic-ish, regarding connections, I flew on four consecutive calendar days in the same direction, all on the next flight available. Houston to Tokyo Tuesday, to Guam Wednesday, to Manila Thursday, to Cebu Friday. Also got to use a three-hyphen word.

Longest non-stop was on a Qantas A380 from Sydney to Dallas-Ft. Worth, about 16.5 hours from wheels up to touchdown. I’ve also had quite a few in the 12-15 hour range, Detroit-Bejing, Atlanta-Dubai, Chicago-Abu Dhabi, Atlanta-Johannesburg, Detroit-Seoul…got a few miles in.

If I may continue on this slight hijack…
In April, my kiddo kept getting additional “OK, now that you’re here, tomorrow fly to X” instructions from his company. As a result, he actually circumnavigated the globe, although inadvertently.

When I was a kiddo in the 60 s , the trans Atlantic prop planes , I seem to recall, From the States to the UK had to stop in Ireland . Also my mother had to wear a dress , girdle, nylons, gloves and a hat. My sister and I wore identical white blouses, skirts, anklets and mary janes.

Hong Kong to Newark, don’t remember the exact details but the current schedule for the flight show 15:45. It just seemed like forever. Economy Plus helped slightly…

Narrowly escaped what I’m certain would be the longest in subjective time. Middle (transatlantic) leg of a trip from Tucson to Tel Aviv - I think around 8 hours. Booked at the last minute, so not much choice of seats. Middle seat in economy, bulkhead. Al least I don’t have to worry about the person right in front of me reclining into my face.

The the fight attendant comes by with some sort of contraption and plugs it into the bulkhead right in front of my seat. “What’s that?” I ask. “A bassinet.” The woman in the aisle seat to my left was traveling alone with an infant. The flight attendant must have noted my look of abject terror - when boarding completed there was one empty aisle seat left and she moved me there.

Around 12 or 13 hours. From Adelaide, South Australia, to Hawaii.

Chicago-Osaka, 13 hours. We were in the back of the plane. I have to say, the back of the plane on an international flight is more comfortable than the back of the plane that we sat in Las Vegas-Atlanta last fall.

I’ve done San Francisco to Seoul half a dozen times once in first class (I was like 7 so I barely remember it besides falling asleep sideways in my seat).

Boston to Munich, Denver to Panama City and other reasonably long flights but like many other my long flight is LAX to Sydney.

I’ll sit anywhere for a short domestic hop, but for a long-haul international flight, I want to be near the front; it gets me off the plane quicker, and also gets me to/through customs quicker.

Detroit to Japan (either Tokyo or Nagoya) is 13+ hours. The first time I did it was about ten years ago, and it was far outside of my normal flying experience; by the end I was actually experiencing low level anxiety, as it was starting to seem like it would never end. Being awake for nearly 24 hours at that point didn’t help either; I just can’t sleep much on a plane. Subsequent flights to Japan no longer incur that sort of anxiety, as I know what to expect from the experience.

Wife flew back from Japan once and diverted to Cleveland because of a major winter storm; they didn’t deplane there, just sat on the tarmac until Detroit opened again, and then flew home. So she ended up spending something close to 17 hours on that plane, with several hours of it being spent in uncertainty about when it would end.
