Most airlines recommend arriving at the airport three hours before departure for international flights. It's common for international flights to start boarding earlier than domestic flights (the aircraft are often larger and have higher passenger capacities), which accounts for the earlier recommendation.
Depending on the requirements of airport authorities, you will need to present a mobile boarding pass, a paper boarding pass printed out by you or a paper boarding pass picked up from the check-in desk.
There are several ways to get a boarding pass. You can get it on the airline's website and print it on paper. Or pull it up on your phone in the airline's app. You can also print it at the airport.
It is always a good idea to check into your flight early, as it can help you avoid any potential delays or issues. Checking in online 24 hours before your flight leaves gives you the opportunity to select your seat and print out boarding passes ahead of time.
What to Do After Online Check-In. Once you receive your electronic boarding pass, you can head straight to security if you're traveling carry-on only. If you're checking a bag, you'll still need to stop by the ticketing area at the airport. Look for special “bag drop” lines that bypass longer check-in lines.
Online check-in allows you to print your boarding pass at the airport. You can print it at a kiosk or the desk. If you can't print your boarding card at the airport, the airline should replace it. Don't worry if you lose or can't print your boarding pass.
The confirmation number for an airline is a 6 character code comprising of letters and numbers. (Example: Airline Confirmation# A1B2C3) You will be able to print a within 24 hours prior to your departure. You can also typically print from airport kiosks at the airport when you arrive on your travel day.
Save the boarding pass to your device for easy access at security and when you board. Make sure the entire barcode is visible on the screen when you show it at security.
Meanwhile, a paper ticket won't tell you when your flight is canceled. Plus, a poorly printed boarding pass can render your ticket useless at the gate. Hoeller points out that printing a paper ticket and neatly folding it into your passport is much easier than juggling between your personal items and phone.
Flyers who are traveling to an international destination should arrive at the airport earlier than domestic flyers. This is because international flights can have additional check-in requirements, like passport verification, that need to be completed before you receive your boarding pass.
Generally speaking, most airlines advise that you arrive at the airport at least 2 hours prior to a domestic flight, and at least 3 hours prior to an international flight.
