Thanks for your message. The luggage allowance on all our tours is 1 piece of checked luggage weighing up to 20kg. This is regardless of the airline's own allowance (including flight upgrades). This is to take into account the wider operational needs of the tour, including ground transportation and porterage. You will need to adhere to this restriction, I'm afraid, even though your flight upgrade allows 2 pieces, each up to 23kg. 

If you have any other questions please reach out and we hope you have a great holiday.

Best wishes,

Just You
