how early you arrive at the airport all depends on which airport you're using.

it's fine to have medicine in your suitcase. do not take any liquids that are in containers bigger than travel-size (meaning, do not take your normal can of shaving cream, it must be the travel sized version...cant remember exact ounces off top of my head)

have all of the travel-sized liquids in a separate, clear zip-lock bag. again, there is a specific size requirement, meaning you can't take a huge freezer bag, but i dont remember the exact size. i just go with the sandwich sized bag with my liquids.

pack the bag in an easy-to-access area of your luggage. when you go through security, you will have to remove the bag and place it into a bin to run through x-ray separate from everything else.

if you're taking a laptop, you will have to remove that also when going through security.

i'd advise wearing shoes that are easy to remove and put back on, because you will have to take those off as well to go through security.

other than that- bring a light jacket, sometimes the plane will be cold, sometimes hot...all depends on who on the plane is whining about the temperature.

you cannot bring a bottle of water or other beverage through security, but once you're through security you can purchase a beverage and take it with you on the plane or in any connecting airports / flights.

if i think of more i will add it.
