Ryanair has reportedly suffered a major systems failure overnight with dozens of complaints of passengers being unable to check in and some planes delayed taking off.
One plane was kept on the tarmac for 90 minutes this morning with passengers being told there had been a 'country-wide systems failure'.
The outage is impacting airport check-in desks across Europe.
Graeme Jolly tweeted: "confusion, chaos and absolute carnage right now at the check-in/bag drop desks at Rome Ciampino. 20minutes so far and no closer to desks. Totally unacceptable."
Another passenger quizzed the airline about a flight taking off.
Romana McCallum wrote: "Why is a flight allowed to leave when the boarding system crashes mid-boarding, leaving passengers at the terminal?
"Only 3/4 of our party made it through and the remaining 1/4 are stuck at Stansted. Utterly irresponsible, expensive and huge waste of time: Why?"

Vicky Graham-Stevenson complained to Ryanair on Twitter .
She said: "can you please tell me why my daughter has just been charged £55 to check in at the airport when she hasn’t been able to check in online due to the website keep kicking her out every time she tried".
One passenger on a Stansted to Faro flight told Mirror Online: "Basically we’ve been on the tarmac for 90 minutes and they say it’s a country wide system failure.
"I've seen people on twitter saying they’re stranded".
Shortly before 8am another passenger tweeted: "is your online check in down? Its saying our booking cant be found and were trying to check in for our flight home tomorrow..."
Ryanair is yet to comment on the disruption on their social media channels and they have been approached for comment.
