When is your return flight?
According to this TUI webpage, you can check in 14 days before your flight:
WHEN CAN I CHECK IN ONLINE?
If you're flying with TUI, online check-in opens 14 days before your flight takes off. You'll need to check in for your outbound and return flights separately. To see if online check-in is ready for your flights yet, visit our Flight Extras website and enter your booking reference, the surname of the lead passenger and your departure date. You'll then be able to click the Check-in button if it's available.
