Routes Over Antarctica.

Fri Aug 23, 2002 2:03 am

There are a ton of routes that take planes over the Polar Region.
Are there any comercial routes that fly over parts of antarctica. I can only think of routes that involve Australia and New Zealand, but don't know if airlines actually fly those routes regularly.
AUK to South Africa, and Sydney to South Africa and South America (EZE, SCL, GIG). As far as I know, these aren't flown regularly by any airline. Is this true.

Qantas operates a four times weekly Sydney-Johannesburg flight with B747-400s. SAA operates a Perth-Johannesburg flight four times a week with B747-200s, B747-300s and B747SPs.

LAN Chile is operating a thrice weekly Sydney-Auckland-Santiago de Chile service with A340-300s.

Aerolineas Argentinas has a twice weekly A340-200 service from Sydney via Auckland to Buenos Aires.

However, I don't know if they fly over antarctica.

Could well be that no scheduled airline flight has ever passed over Antarctica. The "great circles" from Australia to Africa and from New Zealand to South America don't pass that near there, as you can see looking at a globe. And probably no airline has ever flown Perth-Buenos Aires nonstop, or Tahiti-Johannesburg.

Aerolineas Argentinas claims they flew over Antarctica for EZE-AKL-SYD.

I think you mean AKL, not AUK.

Didn't Qantas have a special around the world flight last year? I remember seeing it advertised. That Doesn't count, because it is a chartered flight. I guess the Southern Hemisphere doesn't have enough cities of size.

As Bigo747 said, the AKL-EZE route operated by Aerolineas Argentinas and
formerly by Qantas passed over Antarctica.

Oops, looks like I'm talking past tense there.
Service is still operating.

I don't know why It doesn't fly over Antarctica route. Here it is:

The website says "great circle route map" which means curve route on purpose. Can't you see a red line is curve? The map is flat and route is curve.

I got an example polar route is EWR-HKG real circle map route.

I once flew Aerolineas AKL-EZE-AKL. On the return flight, the trusty old B742 couldn't hold enough gas to make the trip non-stop, so we stopped in Rio Galagos to refuel (I understand this is normal practice). RG is right down the bottom of Argentina toward the tip of South American, so an arc drawn from here to AKL is lower than what is shown on the map above (which shows the route AKL->EZE). I flew back mid winter of about 1996 or 1997 and we definitely flew over icebergs, but not pack ice. Presumably the map shown above shows the outline of land with the white representing the permanent ice shelf? So in the winter time, the line of pack ice would be much further north (????)

By the way, probably the most interesting part about that trip was that although we cleared immigration on departing EZE, we were allowed outside the terminal building at Rio Galegos during the hour or so that the aircraft was being refueled. Myself and another pax caught a taxi and went for a trip into town to check things out. Mind you, it is that desolate and isolated, I guess there's nowhere you can go!

I found it. I just test with map routes. There is no non stop flight between at this time. Example here it is: Perth or Sydney to Buenos Aires across Antarctica route.

What about any flights from Auckland to Cape Town. I did a search, and found the great circle route takes you over Antarctica.
The best one is SCL-PER, but I can't seem to justify it economically. Another problem, and people more knowledgeable please comment, is the ETOPS over Antarctica. I checked, and even the range for 240mins only covers the tips of Antarctica. Can any plane fly outside of that range?
PS. I'm sorry, I don't know how to put the great circle mapper routes on here.

I thought we were talking about real flights here.
There is no Auckland - Capetown service nor is there a Perth or Sydney (non-stop) to Buenos Aires flight.
As far as ETOPS is concerned, I think range limitations would rule out the use of a twin-engined aircraft even before ETOPS became a consideration. Smile

I thought that even four engine aircraft have to keep within range of suitable airports for emergency purposes. How far is that?

I think 4-engine planes can operate anywhere as long as there are alternate airports in the arrival area.
