On routes that fly very far north or very far south, at certain months of the year when these planes are flying, will it stay light or dark (light on night flights like NRT-JFK in summer, dark on JFK-NRT in winter) for the parts of the flight passing flying very far north? I have noticed on all three of my eastbound transatlantic flights a faint light through the whole night off the north facing side of the aircraft. At least I think I have . I don't mean just a little bit though like that where it is definately dark, but there is a light on the horizon. I mean pretty light. Here are some routes that either are currently flown, or have been flown in the last year that I had in mind that could fall under this category:

About 2 years ago I flew PEK-ORD and the sun was on the horizon the entire flight off to the north. It was like there was a sunset for about 7 hours. We left PEK in the afternoon and arrived at ORD in the afternoon. The sun set a bit after we left, just until it was a bright orange glow on the northern horizon, you know the time when the sky is prettiest, then it rose again as we came down over northern Canada was we made our way to Chicago.

Just about any route in Alaska during the summer and winter respectively.
Two nights ago I had to look at sending a Medevac from Anchorage to Northway. Up there this time of year there is no civil twilight hours. On the other hand I sent an aircraft to Seward, and the civil twilight ends and started at 1:00 AM and 3:30 AM respecively.
Also note that the higher in latitude you go the longer the dusk/dawn is. I think it has something to do with the angle the sunlight is hitting the earth. Anyway because of that in Alaska, you can conduct operations Civil Twilight to Civil Twilight, rather then Sunrise to Sunset.
OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

Thank you for all of your responses! I would have loved to have included more routes because especially on flights between the west coast of North America and Europe, there are a bunch of flights that reach latitudes that are very far north. Can you think of any other routes that reach far southern latitudes? The closest besides those two that I put there are between South Africa and South America, but those do not go quite as far south.

Presently operated by ARG 340 aircraft is flight between Rio Gallegos ARG and Auckland NZ which hits close to latitude 75º South... Right now it is winter in this part of the world, the flight is almost entirely night... in December and January, our summer, it is entirely a daylight flight...
