Trans Atlantic Routes, How They Are Determined?

Sun Apr 13, 2014 4:16 pm

Hello everyone -
I'm considering few options for my next flight over the pond to NYC, from either SKP or SKG, and most of the options are either with TK or LH.
Now, I'm tracking some of the flights I can chose in flightaware and I see that two different flights in the same day are taking completely different routes.
For example, if I take TK and they double daily flights, the one in the morning is taking more northern route http://flightaware.com/live/flight/THY3 while the one in the afternoon is taking much more southern route http://flightaware.com/live/flight/THY1, also Lufthansa for example flight DLH412 today is using much southern route http://flightaware.com/live/flight/DLH412 compared to the same flight few days ago when it was taking more northern route http://flightaware.com/live/flight/D.../history/20140409/1335Z/EDDM/KEWR.
I feel much better using that northern route since there is Iceland and Greenland in case something goes wrong compared to the other southern route which is like 90% over water. I flew many times (15+) over the pond and I didn't care so much about the route, but I don't know why I have this phobia nowadays and worry so much about the route instead of enjoying the flight, but I appreciate if someone explains to me why the route is so much different for the same flight on a different day.
Thanks in advance, Laziale

All I say its wind. The winds are changing throughout the day and the computer always calculates available routes (Traffic) , Winds, Miles , Weather, all these 4 Options are considered thats why everyday the flight routes change !
I still miss Trans World Airlines and the L-1011

Due to the volume of traffic, there is a system of tracks across the North Atlantic. They are determined on a daily basis, every flight is assigned a track and follows it across the ocean. Here's much more information, hopefully not too incorrect: http://en.wikipedia.org/wiki/North_Atlantic_Track
Don't cry because it's over, smile because it happened.

What does "like" 90% over water men versus just plain 90% over water? I am questioning the use of the word "like"

Well, if it's not exactly 90% then it will be like 90% or "around" 90%

Those airports in Greenland mostly handle Dash 8s. Only a few handle widebodies.
Just accept that some days, you're the pigeon, and other days the statue

Most twin-engine aircraft crossing the Atlantic can safely fly with an engine inoperative for at least two hours (sometimes more) in case of a mechanical issue. Their flight plan is built accordingly so they're never too far from a suitable airport if necessary.
