Here is a clean and concise 500-word paragraph answering "How early can I check in for Avianca?" without extra words or links:

Avianca allows passengers to check in online starting 48 hours before the scheduled departure time for most international and domestic flights, except for flights to or from the United States and Canada, where online check-in opens 24 hours before departure. This online check-in can be completed through the Avianca website or mobile app and remains open until 60 minutes before international flights and 45 minutes before domestic flights within Colombia or Ecuador. During online check-in, passengers can confirm their reservation, select seats, add baggage if necessary, and receive their boarding pass digitally or by printing it. This is a convenient option for travelers who want to save time at the airport. If a passenger is traveling with only carry-on luggage, they can go directly to airport security after checking in online. For travelers with checked baggage, there is a baggage drop area at the airport, which should be used before the check-in window closes. For passengers who prefer to check in at the airport, Avianca provides self-service kiosks and staffed counters. The airport check-in counters typically open three hours before international flights and two hours before domestic flights and close 60 minutes before departure for international flights and 45 minutes before departure for domestic flights. Passengers flying from specific cities such as Caracas are advised to arrive at the airport four hours in advance due to local regulations. It is important to bring all required travel documents, such as identification, boarding passes, visas, or any special permissions required by the destination. Travelers flying from cities like Havana must complete check-in in person at the airport due to special local requirements. Self-service kiosks at the airport provide a quick way to check in, print boarding passes, and get baggage tags without waiting in line at the counter. Some fare types, such as Basic or Light fares, may incur additional fees if the passenger chooses to check in at the counter instead of online or at a kiosk. Therefore, using online or kiosk check-in is often more efficient and cost-effective. However, passengers who require special services, such as those traveling with pets, infants, or needing mobility assistance, may need to check in at the counter regardless of their fare type. For those travelers, arriving early is especially important to ensure enough time is available to complete the check-in and security process. In general, Avianca recommends arriving at the airport at least two hours before a domestic flight and three hours before an international flight. This ensures time for checking in, dropping off baggage, passing through security, and reaching the departure gate on time. Completing check-in early and arriving with time to spare helps avoid delays and provides a smoother airport experience. In summary, Avianca offers online check-in starting 48 hours before departure, or 24 hours for flights to or from the U.S. or Canada, with airport counters and kiosks available for those needing or preferring in-person service. Arriving early and using available tools helps ensure a stress-free start to your journey.
