If anyone can guide or let me know if it's eligible for compensation il appreciate it
Wed July 24 JFK-ZRH-BUD 20ppl
LX 17 : Original departure time 4:15pm, actual departure time 5:16pm
Original arrival time to ZRH 6:05am, actual arrival time 7:05am
LX 2250: left ZRH 7:20am leaving 20ppl stranded, they were all booked on 1 itinerary.
Checking LX2250 flight history it does show multiple dates leaving later then scheduled departure, I have no clue why they wouldn't wait knowing that there are a group of 20 passengers that needs to make this flight.
Now when trying to rebook, airport agent said there aren't enough seats for 20 so we need to split up, some arrived at Bud 2pm, some 8pm and some next day 8am
I tried this website: Airhelp and it says that there is no compensation for this:

Does anyone know the rules 1) can we get compensation for this and if yes 2) how and where do I claim?
