Manchester Airport bosses have taken to Twitter to share a stark warning as passengers could be refused entry to their booked flights.
The airport has thrown its weight behind a campaign aimed at making sure passengers are safe and responsible. A tweet sent from its official account on Thursday said those travelling from Manchester are "encouraged to fly responsibly".
There was also a link to the One Too Many campaign's website, which warns people could be hit with harsh penalties if they drink too much at the airport.
