Well this will be interesting. We have a very short (1h) connection VIE-LIS-GRU and usually there are delays as well, so best case scenario we will be running and just catch the flight. We will have checked luggage and hand luggage (30l hiking bag), and will have to pack the hand luggage quite full so we can "survive" a few days incase the checked luggage is delayed, which does not seem impossible given the short connection. At least it's 10kg and not 8kg like with LH airlines, but yeah.

Which Boarding Group do Comfort Seats book into? I see that the purchaseable "priority boarding" just books into Zone A and not the Premium Zone, so there could be weighing in Zone A as well I guess?
