SK on a true long haul flight.

Some more good news in all the misery.

Last week SK did the longest nonstop flight ever in their entire history. It was a rescue flight CPH-LIM-CPH. A distance of above 11.000KM. The flight were performed by SE-RSB. The outbound flight took around 14:30 hours. The return flight a little over 15 hours.

This week an even longer flight CPH-ARN-LIM-ARN-CPH is scheduled. This flight is scheduled to be performed by SE-RSA

Also a flight CPH-NAT-GIG-OSL-CPH is scheduled for this week. This flight is scheduled to be performed by SE-RSB

Saw that on the news a couple of days ago - did they have to refuel at LIM?

With a max range of 13,800KM for the A350's I would assume they refueled at LIM

What about SQ's A350 SIN-JFK? I thought it can fly like 20000km?

That has to be an A350-900ULR (as in Ultra Long Range) which can do 9.700nm ~ 17.000km and about 20hrs flight time. SIN-JFK is about 9.500nm-ish. So might work out. Not sure what the regulations there are for fuel reserve. 200nm seems a bit on the low side. I think they need something like 30 to 45mins extra flying time. Assuming flying slow 200nms and 30mins might barely work out.

The regular A350-900 has a maximum range of 8100nms ~ 15.000km

I belive the unit on the 9.500 was supposed to be miles, so closer to 8300 nm, leaving a more reasonable margin on the SIN-JFK route.
Lucky we earn frequent flyer miles based on miles and not nautical miles... (please don't read and enhance SAS and others)..

SQ21/22 is SIN-EWR, the only SQ flights into/out of JFK are SQ25/26 from/to Frankfurt.
The A350-900ULR is an amazing piece of craftsmanship!

True! Good find, didn't think that GCM shows imperial miles not nautical miles by default. 1400nm safety buffer is more than reasonable.

so, why not try SIN-MIA

Also remember that for SIN-EWR, they have tailwind most of the way. And for EWR-SIN, they often choose to fly via Europe to make use of the tailwind. The last flight which is available on Flightaware shows a routing over Stockholm. So, the still air distance is usually shorter than the 8,285 nm great circle distance.

The distance via Stockholm is greater than the 8285nm, just that the winds are more favourable, making the flying time shorter. But more importantly than flying time, less fuel consumption. Which I guess is what you meant...

That's what "still air distance" means, as opposed to ground distance.

Interesting term that I had not encountered before, live and learn.

Note that the A359 can fly much farther if the payload is reduced... the outbound was completely empty and on the inbound they probably only had passengers and only baggage as cargo. That boosts ranges significantly. The SQ ULR has pax and cargo.

Even if the bird was able to fly to LIM and back to Copenhagen without refueling - which it certainly can't - it would be very inefficient/uneconomical to do it. The fuel consumption would by far exceed 2x the outbound fuel consumption. The fuel consumption to carry the fuel for the last part of the return leg would be very high and reduce the pax and cargo load significantly. That is the reason why these ultra longhaul flights are mostly not economically sustainable.
