Provide the check-in agent with identification and flight information. Receive your boarding pass and drop off any bags you are checking. Check your boarding pass for your gate number and proceed to security."
For domestic flights, 2 hours is plenty of time to check-in and get through security to your gate. For international flights, get to the airport 3 hours ahead of your flight.  2-3 hours is a general recommendation and you should check with your airline for specific arrival guidelines.  The amount of time you need to complete check-in will vary based on the size of the airport, day of the week, travel season, and other factors. It’s always a good idea to give yourself more time than you think you need! Most airlines have different lines for different types of travelers, for example, members of rewards programs and first-class flyers get preferential check-in services. Make sure you get in the appropriate line for your booking. If you are checking bags, then you will have to proceed to the check-in counter no matter what to drop off your bag. Depending on your airline and where you are flying to, the staff may ask for your flight number or booking number, or they may be able to check you in with just your ID. Have all your information and documents handy to present to the agent.  If you booked your flight online, print out your confirmation email to provide all your flight information to the airline staff when they check you in. For international flights make sure you have your passport! The airline staff will usually check your bags at the same time they print you your boarding pass. Make sure to grab your baggage tag receipt for when you pick up your bag at your destination. Follow the airport signs directing you to the appropriate security line for your gate. Keep your passport or ID and boarding pass out to present to TSA agents. Be prepared to remove your shoes and any items that have metal as you go through security and make sure that you do not have any prohibited items in your carry-on luggage.
