You can carry one cabin bag weighing up to 10 kg with maximum dimensions of 55cm x 40cm x 20cm, plus 1 small bag up to 35 x 20 x 20 onboard the aircraft.

Due to cabin space limitations only 90 large cabin bags (55 x 40 x 20 cms) can be carried in the cabin, any bags remaining will be carried free of charge in the aircraft hold.
