You might want to have the number of the airline with you at the hotel as well so you can check the status of your flight. You will be able to know if it is delayed due to storms or if it is going to be on time. This could save you a big surprise when you get to the airport and you may be able to switch your flights easier than someone who shows up later. I wish I had done this on my last trip since we were flying during the big storm in early December. I got on a different flight, but due to being there later than everyone else, my friend and I ended up on 2 different ends of a very full plane.
