The dimensions of cabin luggage should not exceed 36x30x27 cm (the total size of all items)
Cabin luggage is not limited by the number and weight of things, but it must be freely placed in a calibrator with a tightly closed lid without using pressure*
Food and goods bought at the airport must be freely placed in the calibrator along with the rest of the cabin luggage!
If you need injections during the flight, you are allowed to take syringes with you on board, but only upon presentation of a medical certificate.
For more information about the rules for the transportation of liquids and other dangerous items, see Appendix 3.
*Alternatively, you can use the carry-on baggage rules based on the Federal Aviation Regulations.
