On the website, I can see that the free allowance is "max 2 baggage pieces with a combined weight 30kg".
Then, in the F.A.Q. :
"I am traveling in a group or with my family, what is our allowance?
Guests in Economy are entitled to 2 baggage pieces with a maximum combined weight 30kg."
So... my parents have to pack and I don't understand if the 30 Kg are the total even for two or more people, or 30Kg for each traveller. I don't fly much, so can someone answer me?
