I was just browsing flightradar 24, I have noticed that most west bound traffic crossing the Atlantic ocean are using a very northerly routing today (Monday, 1600 Zulu), anyone know why?

Probably winds. The NAT tracks are set up for minimum wind west bound, maximum wind east bound.

Most probably winds. It's been like since a few days already. For instance, AC831 has just flown off the tip of Greenland, but last week that same flight flew right over Greenland soil. Also last week, one day AC830 left YUL half an hour late, if not more, and arrived one hour early at its destination.

Yup. The jetstream is currently very wide and strong, and to get around it you need to go pretty far north.

The southern-most track today goes up to 58N (the top of the shaded area). If you go a little further north, you can actually get a bit of a tailwind going west, which will compensate a little bit for the increased distance.

As an airline pilot, you should've known the obvious answer.   Perhaps you were just testing us.

Well it was my first guess, but remember not to many dash 8 pilots are trained to cross the atlantic..

rwy04lga, he's just a kid; as he mentioned, probably has not had a transatlantic crossing yet.

Mir, the graphics are excellent.

There must be some pretty strong westerly winds over the Atlantic these days. As I regularly follow AC 830/831 flights, I noticed eastbound flights going up above Greenland and getting late, while westward flights leaving late arrived either on time or early.

Is that what you meant to say? Strong west winds and eastbound flts late while west bound early. Not usually.

The San Francisco State University maps are excellent and always available. The loop feature is good at showing the recent changes.

No, what I meant to say is westbound flights arrived in Canada on time or early even though they had left late, while those going to Europe followed a more northerly route, producing a detour. Last night's flight flew right over the tip of Greenland, a month or so ago, it was the flight going the opposite way that followed that route. So I guess there are strong east winds over the Atlantic.

I flew on AC831 GVA-YUL on February 22. It left about half an hour late but arrived 10 minutes early. The captain said the delayed departure was due to unusual winds on the eastbound flight and the resulting arrival about 45 minutes late.
