Airport with the longest average flight time for departures?

Thu Oct 17, 2019 7:18 pm

I was just thinking about what airport in the world has the highest average flight time for departures. DXB came to mind first. What do you guys think?

That’s a good guess. How about Easter Island?

JNB would be my guess.

Sydney or Auckland ?

I would say somewhere isolated but with very few departures, maybe somewhere in the Canadian or Russian north?

I would suspect a fairly remote airport with no close (~1500 miles) destinations. DXB, JNB, SYD, and AKL all have destinations with relatively short flight times.

Both have a fair number of relatively short domestic flights. SYD-MEL is less than 500 miles and has literally dozens of flights per day. That drags way down on the average.

The math here is fairly simple: long flights don't really matter if they're counterbalanced by a huge mass of relatively short flights. It's almost certainly going to be an island with flights to very few places, and only ones quite a distance away. For example, look at the scheduled flights from SEZ: other than a single domestic run, all the flights are well over 1,000 miles (alas, that one domestic run operates quite often, which drags the average down). RUN is a pretty similar deal. But I think the winner is (at least for scheduled commercial flights) - as mentioned - IPC on Easter Island. Two destinations, the closer of which is over 2,300 miles.

For example, DXB is a good shout, except that compared to a place like IPC the huge number of flights to India are actually dragging the average down, as are flights to places like KWI, which is around 500 miles and gets 20+ flights per day.

No way, not with all the flights to the other islands. Again, HNL-KOA is like 160 miles and has 20-ish flights per day.

destination, flights per week, distance, distance x flights

OGG 378 87 32886
KOA 211 142 29962
MKK 199 47 9353
LIH 189 89 16821
ITO 164 188 30832
JHM 152 6175 938600

NRT 80 3318 265440
SFO 65 2084 135460
LNY 52 63 3276

I worked out the average stage length to be 1087 nm per departure. Wilkins in Antarctica only sees flights to Hobart as far as I know, that is 1852 nm per departure.

This is why a place like HNL is offset by all of the interisland flights. While not regularly scheduled all year, or public flights, how about from some of the Antarctica airports.

Folks, to simplify this, you're not necessarily looking for airports with a lot of extremely long flights, just ones with very few short ones. For example - and having not done the math - I'd bet that the average stage length from KEF is longer than almost any other hub airport, because there is only one domestic destination flown (seasonally). Almost everything else is 800 miles+. And that's without any extremely long flights, just a near-absence of short ones.

And with that title which confused me, I thought it might mean the airport with the longest time average from pushback to takeoff. Would be another interesting statistic.

That was my first thought. Only flights are to Papeete (2600mi) and Santiago (2300mi).

Historically and again in the future, my guess would be Ascension Island.

Right now the Falkland Airlink flights operate via Sal, but by 2022 they will return. Once they do the average sector will be 2,579nm - including the monthly flight to St Helena operate by Airlink. However I don't think that is returning for 2020, meaning the average sector will be 3,518nm.

Flights aren't really civilian though. But would probably be a winner!

Probably not because there are a lot of inter-island flights from PPT to other islands in the atoll and those flights are far more plentiful than the international flights to and from the archipelago. But IPC is probably up there.

It probably isn't DXB because DXB has a lot of shorter regional flights.

I had those in mind too, but even the Air Tahiti network is pretty long. There are only a few routes of less than an hour, some over 3.

Well, we get into a question of how we precisely define this measure. Is it calculated by dividing the average distance to destination airport by total number of departures from a given airport (say PPT)? Or is it calculated by counting each route once irrespective of frequency and finding the average distance? Given that PPT has several daily departures to many of the closer islands, that distinction will make a difference.

They are operated as a publicly available charter by Air Tanker - a UK charter carrier with IATA code 9L, so I would argue they definitely count.

However the question posed here is regarding the highest average flight time. By definition you can't calculate an average from a sample size of one, so airports with a single service can't be considered - they need to have two or more.

By which definition? Im genuinely interested as I've been taking plenty of statistics-related classes and I've never come across that definitive limitation. Maybe I didn't pay enough attention.

The way I understood it, the arithmetic mean (average) is simply defined as (sum of values 1 through n) / n and I've never heard of a qualifying condition that n can't be equal to 1.
So the "average" stage length of an airport with one flight should just be that one flight's distance.
