Flight seatings booked

I really want to know were I am going to sit when on a plane. Usually I want a window seat as I like looking out and see the world below, sometimes there such an amazing views that blows your mind.
I also take some photos and videos as well.
So now I have booked my seatings for all but one flight, it was not available, I do not know why!?!?
On some of the flights there were not much to chose from but I got some good seats I think.

Below is all the cities I will visit.

To all of you, enjoy life and have a nice day!
