Passengers are not happy.

Many passengers experienced an array of delays and flight cancellations last night as snow and ice hit Dublin Airport. There were a number of de-icing issues with planes which meant people had no choice but to sit on the ground, or indeed sleep on the floors. However, during the snow storm, the airport tweeted that it was "open and operational," but that lead to many disgruntled customers.

.@DublinAirport is open & operational. Some airlines are experiencing delays to their flight schedules as a result of de-icing issues. Passengers are advised to check with their airline for latest flight updates. We apologise for any inconvenience caused.

Pictures and comments flooded social media last night as people prepared to stay in the airport for hours. Ryanair tweeted:

Weather has regrettably caused a small number of Dublin cancellations (3/3). All those affected were advised of their rebook/refund options

And these were the kinds of reply the tweet received:

Can SOMEONE let passengers know what’s going on with flights delayed from yesterday? We have been left in the airport with no food, drinks & no idea when we can travel..?

Been in Dub Airport for 11 hours now because you didn't decide to tell us the flight to Amsterdam was cancelled for 3 and a half hours, then had to pay €400 for an aer Lingus flight at 6.15am and I still haven't spoke to a single person from Ryanair, Michael prefers his horses

We are stuck in Dublin with hundreds of other folk. Basically dumped off the plane - off you go. No staff members to tell us where to go or what to do. We basically overheard a conversation with an airport official. Really poor customer service.

A small number ? Seriously lads between you and @DublinAirport - was anyone from your #Twitter accounts in touch with anyone in #dublinairport? Where are you tweeting from? Space? Hundreds stranded. No updates other than *fully open*
