When flying with Ethiopian Airlines, knowing how early you can check in is key to ensuring a smooth and stress-free departure. Ethiopian Airlines offers flexible and convenient check-in options for passengers, including online check-in, mobile check-in, airport counter check-in, and self-service kiosks at select airports. If you choose to check in online, Ethiopian Airlines allows passengers to do so up to 36 hours before the scheduled departure of international flights and up to 24 hours before departure for flights departing from Addis Ababa Bole International Airport (ADD). Online check-in is accessible through the official Ethiopian Airlines website and the mobile app, allowing travelers to confirm their booking, choose seats, and receive their boarding pass digitally. This option closes 2 hours before the flight, giving ample time to avoid airport lines and delays. For travelers with only carry-on luggage, completing online check-in means you can proceed directly to security upon arrival. If you have checked baggage, you can still take advantage of online check-in and simply drop off your bags at the airport bag drop counter, which generally opens 3 hours before the flight and closes 1 hour before departure for most international routes. For passengers who prefer checking in at the airport, Ethiopian Airlines airport counters typically open 3 to 4 hours before international flights, depending on the departure airport and region. The airline strongly recommends arriving at the airport at least 3 hours before your scheduled flight time for international travel and 2 hours before domestic flights, to allow enough time for check-in, security checks, immigration procedures, and boarding. This is especially important during peak travel periods or from busy hubs like Addis Ababa, Johannesburg, London Heathrow, or Washington D.C., where longer queues can delay the process. For added comfort, Cloud Nine (Business Class) passengers and ShebaMiles frequent flyer elite members enjoy access to dedicated priority check-in counters, streamlining the experience further. Travelers needing special assistance, traveling with infants, or carrying oversized baggage must check in at the airport, as additional processing may be required. Additionally, if your flight is operated in partnership with another airline or as part of a codeshare agreement, check-in rules may differ, so it's always best to confirm with the operating carrier. Ethiopian Airlines may also require passengers to check in at the airport if travel documents, such as visas or health certifications, need verification. To get the best seat options and avoid any last-minute stress, it’s recommended to check in as soon as the check-in window opens. In conclusion, Ethiopian Airlines lets passengers check in online up to 36 hours before departure, while airport counters open about 3 to 4 hours prior to international flights. Checking in early not only ensures smooth boarding but also gives you peace of mind on your journey. Whether you fly Economy or Cloud Nine, early check-in with Ethiopian Airlines is the smart way to start your trip right.
