Any delay beyond 3 hours is not acceptable. The plane should be brought back and passengers deplaned. The pilot should be aware of the average and maximum tarmac delay for the flight and take the decision. The passengers has to right to know the delay. My problem is that the passengers are not kept informed. When a prolonged delay happen, since the seat belt sign is on the lavatories are closed by the staff and passengers not give the basic amenities. This should be avoided on delays that are more than 90 minutes.
