If you encounter an error during online check-in, this may be due to an issue with our systems, or simply restrictions from your destination of travel. Please don't worry, head to the TUI check-in counter upon arrival at the airport where our TUI Team will validate your travel documents, collect your bags and issue your boarding passes. No need to contact us, we can check you in at the airport, free of charge. Check-in opens at least two-and-half hours before departure for short and mid-haul flights, and at least three-and-a-half hours before departure for long-haul flights.
