OP - It would be very helpful if you could explain to us several things and ask someone who is fluent in English to help you write your next post. That is by no means an insult. If this were a board conducted in Albanian, I can assure you that I would be seeking assistance from someone fluent in Albanian.
People jumping to conclusions about whether EC 261/2004 applies and if it does, what is owed, are doing just that: jumping to conclusions without any information.
1. Why was your original flight from Tirana to Vienna cancelled? The exact reason really matters. If nobody would answer you, that is fine.
2. If your flight to Vienna had not been cancelled and you had made your connection to New Jersey from Vienna, what time was the flight scheduled to arrive in New Jersey?
3. If you had been able to fly via London, what time would you have arrived in New Jersey?
4. When did you actually arrive in New Jersey on the flight from Munich?
Will look forward to hearing from you.
