The cabin allowance is the consistent part

TUI includes an underseat bag and a 55 × 40 × 20cm cabin bag at 10kg on every fare. Whether you have booked a package holiday or a flight-only seat, that cabin allowance stays the same.

The hold allowance is where TUI bookings differ, and it depends on your package rather than a single published rule.

Check your booking for the hold allowance

Package allowances vary, typically in the region of 20 to 25kg, and no single bag may exceed 25kg. Your confirmation is the authority — not a general guide, including this one.

If you are choosing a checked case, work from the weight on your own booking rather than an assumed figure.

Both cabin bags are included

The 10kg cabin limit covers the case and everything in it. A hard-shell cabin case at this size weighs around 2.5kg empty, leaving roughly 7.5kg for contents.

The underseat bag at 40 × 30 × 20cm is deep enough for a small wheeled case, so a two-case combination works well on TUI.

Family travel

On family bookings, one large checked case shared between two people is usually more efficient than two mediums — fewer bags to move, and the weight allowance pools more usefully. Just keep any single case under 25kg.
