Will the flight notification delay return to normal?

Yes But whether it can return to normal as scheduled depends on the reason of flight delay. If the flight is delayed due to weather or other unexpected events, the time to return to normal will be affected by uncertain factors, and there will be delays or cancellations. If the flight delay is caused by mechanical failure or other human factors, the airline or airport will try its best to repair or solve the problem and return to normal in the shortest time.
