Arrive at least 2 hours before your scheduled departure. This may seem excessive, but it will give you plenty of time to check in, go through security, find your gate, and account for any unexpected delays. The last thing you want is to miss your flight because you cut it too close.

Do your research beforehand. Check with your airline to make sure you understand their baggage policy, including size and weight restrictions. Be aware of what you can and can’t bring through security. Familiarize yourself with the layout of the airport terminal so you know exactly where you need to go. The more prepared you are, the less stressed you’ll feel.

Pack strategically. Put any liquids, gels or pastes in a separate bag to quickly access for the security check. Wear shoes that are easy to slip on and off. Place valuables in your carry-on rather than checked bags. Have essential documents handy. The key is making the screening process as efficient as possible.

Look for the longest security line. This may seem counterintuitive but the longest line often moves the fastest because more agents are usually working it. Unless you have TSA PreCheck, you’ll have to go through regular security, so choose wisely.

Don’t be afraid to ask for help. Airport staff are there to assist you. If you have a question about directions, your gate location or departure time, don’t hesitate to ask. It’s better to ask and ensure you end up in the right place at the right time.

Bring snacks, water and entertainment. Food options beyond security are often limited and expensive. Having snacks will tide you over if there are delays or long layovers. Staying hydrated and occupied will make the time pass more quickly.

Try to relax. Traveling through major airports can be stressful. Do your best to remain patient and calm. Getting worked up will likely only make the situation feel more chaotic and frenzied. Take deep breaths and remember that any hassles are only temporary.

Allow extra time for connections. If you have a connecting flight, you’ll need to disembark, find your next departure gate and possibly go through security again. Two hours is a good buffer, especially if your connection involves switching terminals. Rushing between flights is no fun and risky.

Be polite to agents and staff. Airport employees deal with stressed out and impatient travelers all day long. Maintaining a courteous attitude will make their job easier and they’ll likely be more inclined to help you out. Say please, thank you, and smile. Kindness is contagious.

Don’t forget about your departure airport. All these tips apply for both your departing and arriving airport. Give yourself plenty of time for checking in, checking bags and security on the outbound portion of your trip as well. Start your journey off on the right foot by being prepared for both ends of your travels.
