Manchester Airport has hit headlines in recent weeks and months as passengers bemoaned waiting in long queues at security.
For months, people have been told to arrive at the airport earlier to ensure they make their flights. However, airport bosses have recently urged those travelling not to arrive too early, as this can also cause problems.
A tweet sent from the airport's official account last week said: "Passengers should not arrive more than three hours before their flight. Those who arrive earlier may be asked to wait away from the check-in area until the recommended time, to reduce waiting times in security and the departure lounge."
