This is our first ever vacation and the closer it gets the more nervous i am getting instead of excited. Can you tell me what I am supposed to do when I get to the airport? Check bags, go through security, and how do I board the plane? We will have 3 kids DD7, DS5 and DD15months. Will we get to board first? Where do I go when i get on the plane if there are not assigned seats? Do i go to the front or do I sit near the back, which is better? I would perfer if a wing weren't blocking our veiw. Sorry for all the questions and TIA for all you help!!
