Ethiopian Airlines offers online check-in starting 24 hours before the flight’s scheduled departure. Passengers can use the airline’s website or mobile app to check in, select seats, and print or download boarding passes. At the airport, check-in counters open approximately three hours before international flights and two hours before domestic flights, closing one hour before departure. Passengers traveling with checked baggage must ensure their bags are dropped off well before the cutoff time, generally 60 minutes before the flight. Online check-in is recommended to save time at the airport, especially during busy travel days. If you miss online check-in, you can still check in at the airport counters or kiosks, but arriving early is crucial to avoid any last-minute issues.
