Choose a paid seat during booking or add it through Flight Extras or web check-in. Without a choice, a seat is assigned free at check-in. Eligible TUI Card bookings include ordinary selection, with organiser restrictions; Comfort and XL seats are excluded. Operational or safety changes can alter the assignment; the current conditions provide a refund if a paid request cannot be honoured.
You must be at least 14 and able and willing to assist. You must understand, speak and read German or English. Exclusions include pregnancy, cabin animals, restricted mobility, caring for someone needing help, and a seat-belt extension. The current X3 conditions also exclude passengers who have booked an additional seat. Crew decide eligibility.
One small bag up to 40 × 30 × 20 cm and 6 kg is included and goes under the seat. A larger bag up to 55 × 40 × 20 cm and 10 kg needs the appropriate booking allowance or an added cabin-bag purchase. Children under two have no separate cabin-bag entitlement under the published X3 help rules.
