For sure the will tell you the the newest up date when you check in.
I would leeve some space in my Bag or backpack in case I have to change items from my handluggage.
What can the say if you carry a empty waterbottle in you handluggage?let it fill up as soon as you are in the plane.
What I hate most, if the dont let you take 2 pieces of handl.anymore.I wonder if the will change from 20 kg to 30kg free luggage,till now 20 + 10 handl.
Would not be surprised the Airlines keep this as it is right now and charge more overweight.
