What can I do at the airport?
When you get to the airport there are a lot of things you can do.  You can eat a meal, stand at the window of the terminal and watch planes land and take off, or play.  You can also sit and read a good book, meditate, drink alcohol,  exercise by walking between different terminals, or get to know someone new sitting next you.  If none of these things interest you then you can also work on your smartphone or computer, watch a movie on them, browse pictures and images, or play game.
