Luggage
Check before leaving to see how many carry-on bags the airline allows and if they have a charge for check-in baggage. Some airlines charge $15 to $20 for each checked bag. Avoid this charge by only using carry ons when possible, or fly Southwest Airlines, where they don't charge a fee for the first two checked bags. Also, be sure to measure the dimensions and weight of your luggage before departing to make sure it meets airline requirements.
Carry Ons
Make sure carry-on items meet airline standards, both in dimension and weight. Also, as of 2009 there is still a federal regulation that prevents the carry on of liquids 3 ounces or more, along with many commonly used household and bathroom items, such as nail files and letter openers. Make sure there are none of these in your carry-on bag to avoid having them taken by airport officials.
Parking
Figure out parking lot locations and prices before departing for the airport. For long trips, it may be best to have a friend or colleague take you to the airport in order to avoid large parking fees. Also, planning which lot to park in can help you choose the most efficient way to get to your terminal.
Arrival time
Plan on arriving at the airport at least 90 minutes ahead of your flight departure, or more if you have to walk or ride a long distance from the parking lot or if it's a large airport. Some travelers prefer to get to the airport two hours ahead of time; it just depends on if you have to check your bags, traffic and if it's on or around a major holiday, such as Christmas.
Checking In
Most major airlines now offer online check in before you even get to the airport. Check in on the airline's website with your confirmation number and personal information, and print out a barcode that the airline staff will use to let you on the plane and check your baggage, if you have any. This saves the time it takes waiting in line to get checked in by a staff member.
