Surprisingly disfunctional operations at Haneda Airport. Flight was delayed and passengers could not check-in due to the change of aircraft on 4/24/2019, but the flight status remained showing on time and passengers could check-in on the screen. Waited over one hours but was given wrong instructions from 5 different staff members, such as directed me to the wrong counter for waiting, or asked me to do self-service check-in while the aircraft was not ready. I requested to file a formal complain to a manager there, but was ignored. This is not the service quality I expected from ANA.
