Hey there!! If you are a new flight goer, you certainly must book a window seat. Avoid seats 18 to 20, as they cover up the wings portion. you would hardly be able to enjoy the spectacular view. You can either book front seats or just go for middle ones, starting from 21 to 35.. Each of them is great and gives you the view for your journey!
Window seat on planes are in lanes of A and F only. Any no of A and F line you will get window seat. If you want to have wings view then 9 to 20 is the no. And if you wish to have some part of wings and clear view then 21 to 29 is best.
