Hello,
Can you tell me why the flight trajectory goes counter clockwise? Even in daytime, at some moment the sun appears at the right side of the cockpit glass?
Isn't the sun supposed to stay at the left side of the airplane all the time?

Is the globe map wrong?

The sun rises in the northeast and sets in the northwest. The route to Hong Kong From SFO starts out heading NW. If the flight departed in the morning the sun would be out the right window. The route heading into Hong Kong finishes heading SW, so the sun setting in the NW would also be out the right window. I'm assuming you're not a pilot, so google "great circle route" to understand why the route appears to be a curved line.

It departed from America so obviously it was America airlines. Duh. Welcome to how the public thinks. Scary, ain't it? And they can vote, too.

Look at the departure time and arrival time. If you leave at 10:00 AM and arrive at 4:00 PM you start out with the sun on your right as you climb northbound and you descend with the sun on your right. During the flight the sun starts on the right, goes behind you, spends hours on your left, goes ahead of you, and is on your right as you land.

Either that or it was the two bean burritos I had before boarding. ;)

Honestly now I'm even more confused

Flights to Asia go NNW or N on departure from DFW. In the morning that puts the sun on your right. At noon it's overhead but you might be heading NW or N. If you're flying north the sun is behind you. The sun continues it's westward journey as the flight starts turning west. If your route is north of Alaska you're heading SW when you enter Siberia. The sun is on your left. In China it's almost due south. The usual route is west of Beijing. Since it's the afternoon the sun is now on the right.

The pure great circle route is right into the usual winds so the usual route westbound is further north into lighter winds. If you get farther north, up to 180 nm from the north pole, the winds as you 'descent' in Siberia and China might actually be tail winds.

The Earth is round going to have to get over this flat Earth thing.

But, but...the moon landing was a fake, little green men from Mars built the pyramids, and chem trails are real. (I have heard all of them from PAX.)

Thanks for that. It brought back quite a few Zima memories that were locked away for a long time.

But this is based on a spherical Earth. Fake news.

Yeah, just read these informative links and if I had to actually calculate any of this stuff, I'd be a plumber instead of a pilot :D. Follow the line on the MFD.
