For a frequent traveler it is a given that you will spend 2 to 3 hours in the airport in waiting for the check-in. You need to have something to do so that you will not get bored. Excessive waiting is stressful. I have an app of crossword puzzle in my phone that would somehow make me busy in the airport. I also bring a comic book but I read that when I am on the plane. Some other passengers that I see would be eating lunch right in the waiting area. What do you do when you are waiting for your flight?
