I flew recently and when getting the ticket at the check in stand, they weighed my carry on. It was underweight so everything was fine. Later when boarding the flight they did not weight the bags again, so anything I bought at the duty free was fine.
Sometimes I bring food with me to eat during my ~3 hours at the airport. If I am travelling with the family, the food can weight quite a bit. Due to the recent issues with receiving the check in luggage, I would prefer to fly only with carry on and carefully fill it to the max.
What would happen if during check-in my bag was too heavy, but I planned on eating and lightening it before boarding? Will they refuse to give me my boarding pass?
(now an absurd followup question) Assuming that the above excuse is good, I noticed that they did not weight my bag at boarding. If I was grossly overweight with, what I (falsely) claimed to be kilograms of food, would I be able to use the same excuse?
