How online check-in works
Kosmos allows online check-in for passengers, reducing time spent at the airport. Online check-in typically opens 24 hours before departure and closes 1–2 hours before flight time depending on the route and airport. Check the airline's website or reservation confirmation for exact cut-off times for your specific flight.
- Visit cosmos.aero and access the check-in section
- Enter your booking reference and passenger last name
- Select your seat from available options (if not pre-assigned)
- Review baggage information and special services
- Complete the process and save or print your boarding pass
Practical tip: Complete online check-in as early as possible to secure preferred seating and ensure you have time to resolve any issues before airport closure windows.
