Can someone help me out. I am confused about the boarding process. I understand I will arrive at the terminal and check my luggage. I also understand that I will hold onto my carry-on luggage. I have read posts that in my carry on luggage I should have a number of items in case my luggage is lost or late arriving to my cabin. THis would include a change of clothes, medicine, bathing suits, etc. In adddition I have also read about people bringing on supplies, ie cases of soda, snacks. SO here is my question how do you manage to carry all of the stuff on and how do you manage to lug it all around when you are doing the resservation shuffle. Thanks !
