A number of flights have been delayed and even diverted at Glasgow Airport, throwing holidaymakers' travel plans into chaos today.
The airport confirmed two flights scheduled to arrive at Glasgow have been diverted to Prestwick Airport instead.
It's understood a 'shortage of air traffic controllers' on the ground has sparked problem today.
Some travellers have even been grounded on the runway inside a "hot plane" while ATC workers "take a break".
SNP MP Angus MacNeil tweeted: "Flights delayed at Glasgow Airport - shortage of air traffic controllers and those ATCs that are there are needing to take a break says the pilot."

A passenger replied: "I’m in one!! Currently sat on a hot grounded plane. ATC at Glasgow are short staffed and those working needed a break. Not enough fuel to hold for 45 mins."
One passenger told The Scottish Sun: "We were due on an EasyJet flight to Gatwick at 10.30am but you could see from the flight tracker that the incoming flight suddenly got diverted to Prestwick. Then there were announcements about the airfield being closed and no explanation.
"Flights are being delayed for about 90 minutes by the looks of it. The airport is busy with holidaymakers and people aren’t happy.”
A Glasgow Airport spokesperson said: “Operations were suspended between 10 and 10:30am due to a localised air traffic control issue.
"This resulted in a small number of short delays and two inbound aircraft being to divert to Prestwick. Both flights returned to Glasgow Airport.
“We would like to apologise to our passengers for any inconvenience caused and thank them for their patience.”
