WHAT DOES THAI PEOPLE TRY SURSTRöMMING MEAN?

Airlines will never allow for people to hold surströmming on flights. Due to high pressure within the can as well as the lower strain inside the cabin, the higher stress differential can lead to some cans rupturing, spewing the smelly liquid in to the aircraft…and it isn’t as if you can leave a airplane while its traveling or open up a window.
