Belfast International Airport has been criticised after passengers turning up to catch early morning flights were faced with "queues out the door".
One passenger who arrived at the airport in the early hours of Tuesday morning described a scene of "total bedlam".
They said there was a long queue at one of the car parks outside the airport, which caused a road blockage at 5am.

Then when they reached the terminal, they said the line for security was "all the way down the stairs".
They added: "We got away ok only because we had fast track. Others in our party had to get new flights."
Another reader said: "Usual chaos at Belfast International Airport this morning with queues out the door."
A Belfast International Airport spokesperson told Belfast Live : "While it was a busy morning, passengers moved well through the security search area and queues had reduced by 6:30am.
"We would like to remind passengers of the importance of arriving well in advance, at least two hours before their flight departs, and coming to the airport fully prepared with all relevant documentation.

It comes as some passengers at the airport have faced disruption with long flight delays.
Some holidaymakers have said they experienced "chaos" when TUI and EasyJet flights to destinations including Gatwick, Bristol, Liverpool Malaga, Kos and Faro were all disrupted in recent days.
The cancellation of the flights left hundreds of people stranded at the airport.
Both airlines have since apologised to customers for the inconvenience.
The Consumer Council has reminded those impacted by cancelled flights in and out of Northern Ireland of their consumer rights.
Richard Williams, Head of Transport at the Consumer Council said: “Passengers who have been affected by cancelled flights should be offered a full refund within seven days, or re-routing via alternative transportation at the earliest opportunity by the airline.
“Our advice to passengers is to seek the travel option that best suits them when they are arranging alternative travel with their airline.”
He added: “Passengers should be aware that they may also be entitled to compensation due to their flight being cancelled. To claim compensation, passengers can complete an online form on easyJet or TUI’s website.
“If passengers remain dissatisfied with the airline’s response, they can get in touch with the Consumer Council by calling 0800 121 6022 or by emailing contact@consumercouncil.org.uk and we will take up the complaint on their behalf.”
