You want to head for the gate with the swagger of a seasoned traveler, but that's hard to pull off when you don't know how much it costs to check a bag, or what to expect when you go through airport security.
Check the airline's luggage requirements
It’s easy to overpack — but if you do, it could cost you. Before your flight, visit your airline’s website to review luggage size and weight restrictions, as well as baggage fees.
Pack essentials in your carry-on
You'll also want to pack some in-flight entertainment, such as your laptop, headphones and a book or magazine.
Arrive at the airport two hours early

Respect other passengers' space
These days, flights are generally fully booked, and most seats offer limited legroom. This might stress out your fellow flyers, so be sensitive.
