Great news...
Earlier we told you that a hen party due to fly to Dublin from East Midlands Airport had been split up due to the disruption.
Anna Hindmarsh told the BBC 13 people arrived on Friday morning to get a flight for her sister's four-day celebration.
The bride and six others were able to board the plane, but those with luggage to check in were delayed and missed their flight because their cases were being manually processed.
However, the remaining six - including the maid of honour - will now join them tonight after a long wait in the airport.

The NHS Derby and Derbyshire integrated care board (ICB) has issued an update on the global IT outage.
It says some NHS services are impacted, and an issue with EMIS - an appointment and patient record system - is causing some disruption in some GP practices.
"The NHS has long standing measures in place to manage the disruption, including using paper patient records and handwritten prescriptions, and the usual phone systems to contact your GP," it said.
"There is currently no known impact on 999 or emergency services, so people should use these services as they usually would.
"Please be patient with your local NHS services while we are working to resolve the issue."

"We know what the issue is... and have resolved the issue," said George Kurtz.
Asked how long it would take for systems to return to normal, he told the US network: "It could be some time for some systems that just automatically won't recover, but it is our mission... to make sure every customer is fully recovered."

A passenger who flew to East Midlands airport today has said departing from Alicante in Spain was "absolute chaos".
Andrea Selby, of Mansfield in Nottinghamshire, said: "There were queues from getting through the door.
"[There were] a lot of frayed tempers as a lot of people didn't know what to do.
"They have had to handwrite all the baggage, the cases."
She added: "Nothing electronic was working.
"I had to carry my case to the airport steps before it was taken off me. With being on my own, that was a struggle.
"Once on the plane, we had lost our slot so then had to wait an hour for another."
She said the heat was "stifling" on the plane.
She added once she arrived at East Midlands Airport, everything was "lovely" and they got "straight through".

Here are some more photos of nervous travellers hoping they will be able to get away on their holidays on time despite the ongoing IT issues at East Midlands Airport.
The airport says although check-in is taking longer, no cancellations are anticipated.

Cyber-security experts are warning that, although there is now a software fix, it’s going to take a huge amount of work to get computers back up and running.
Crowdstrike's bad software causes systems to "blue screen" and crash, which means they can't restart to get the good update on to computers.
Researcher Kevin Beaumont said: "As systems no longer start, impacted systems will need to be started in 'safe mode', to remove the faulty update.
"This is incredibly time-consuming and will take organisations days to do at scale. Essentially we have one of the world's highest impact IT incidents caused by a cyber-security vendor."

Officials covering various sectors have met in the emergency Cobra unit and they are updating ministers.
The prime minister's deputy official spokeswoman said that according to a statement from Crowdstrike, this was not a security incident and a "fix had been deployed".
She added there had been no impact on 999 services and she wasn't aware of anything impacting normal government business. Ministers will continue to monitor the situation.
