You can check in for an Avianca flight starting 48 hours before departure for most international and domestic flights. If your flight is to or from the United States, Canada, or Puerto Rico, online check-in opens 24 hours before departure. Online check-in closes 60 minutes before departure for international flights and 45 minutes before departure for domestic flights within Colombia or Ecuador. You can check in online through the Avianca website or mobile app. After checking in, you can download or print your boarding pass. If you have checked baggage, you must still go to the baggage drop counter. These counters open 3 hours before international flights and 2 hours before domestic flights and close 60 minutes before international and 45 minutes before domestic flights. Passengers with basic or light fares may need to pay a fee if they choose to check in at the airport instead of online. Self-service kiosks are also available at many airports and allow you to check in and print bag tags. Some passengers, such as those traveling with pets, infants, or requiring special assistance, must check in at the airport counter regardless of fare or online check-in. Flights to certain destinations, like Havana, also require airport check-in. If your booking includes multiple passengers under the same reservation, one person must complete the check-in for the entire group. For codeshare flights or those involving other airlines, check-in may only be available through the operating carrier. Travelers are advised to arrive at the airport at least 3 hours before international flights and 2 hours before domestic flights to allow time for check-in, baggage drop, security checks, and boarding. In some cases, such as flights from certain airports or when visa documentation is required, online check-in may not be available, and you will need to check in at the counter. Always confirm check-in requirements for your specific route to ensure a smooth travel experience.
