Transatlantic routes

Post by sn26567 » 10 Aug 2018, 17:38

DL43 and SN501, both flying from BRU to JFK today at approximately the same time, have taken quite different routes over the Atlantic, Delta flying much more North than SN.

Can someone explain why? The winds are the same for everybody!

I don't know, perhaps a difference in assigned flight level / altitude?

It can be due to different ETOPS qualifications.
Or ATC restrictions.

As I see on flightaware, flight time for both flights were approx the same.

So many flights across the pond for the assigned tracks.

Screenshot 2018-08-10 18.59.29.png
Green lines are the Westbound tracks for 10AUG 1130-1900Z
Blue lines are for 11AUG 0100-0800Z.


Below is a screenshot from FR24 at 1900Z for flights into KJFK, and this is only the late wave and only into KJFK.
Just add the flights to all other NAM destinations ...

SN got a much better cruising level out of this, FL370 compared to FL340 and mid-atlantic FL320 for DL until it got out of 'Gander Oceanic'. So probably some oceanic track congestion also played a role in the decision making.
