First for carryons, it looks like one rollerboard that weights 7kg and free "personal items" like purse, laptop bag, etc. My wife will be doing rollerboard and purse- easy enough. But then there's me: If I were doing a domestic flight, I'd do my rollerboard and my laptop backpack that I stuff under the seat. However, this looks a bit more strict where that laptop bag might need to be just a little shoulder laptop bag. Or am I being overly paranoid about that second bag- what are the limits? And if I take my laptop bag and they don't allow it- does it get gate checked? Do I get charged for it (and how much)?
