Recently I faced an extraordinary situation during my flight inside the EU. A very large group of passengers (80% of all passengers, mostly men, probably football fans) already quite drunk during boarding, was behaving against safety instructions. They occupied the lavatory before and during take-off, creating a constant huge line to the WC, which prevented the crew from explaining the safety instructions normally, delivering the snacks and beverages (the corridor was occupied during the whole flight - 1.5 hours), and was generally behaving far beyond any regulations.
Some of them were also smoking, shouting and bothering other passengers. The cabin crew was obviously not able to deal with the situation (they didn't really try) and started selling alcohol to already very drunk passengers, which of course, escalated the whole situation.
I never had such a creepy flight and don't really know what a passenger can do in such situation. Is there any law that protects the passengers in such cases? I just want to know, if there is any chance to get a compensation for this flight, and/or at least to prevent such cases in future
Thanks a million for your replies.
