Ryanair is closing their Glasgow Airport base, it has been reported.
Over 300 jobs are at risk with Ryanair flight routes from the airport reducing from 23 to just three.
The routes which remain are to Dublin, Wroclaw and Krakow, whilst the airline will be adding 11 new routes to Edinburgh.
Chief commercial officer David O’Brien cited Brexit was causing problems to Scottish tourism and hence their need to leave the airport.
The Scottish government proposed lowering air departure tax costs and replacing air passenger duty costs.
Yet this has yet to be implemented, needing EU approval.
He explained: “We think Brexit is particularly threatening to Scotland and its economy, and particularly to the aviation industry.
“The weaker Scottish economy is even weaker in Glasgow and we simply can’t bear the air passenger duty of £13.”
A Glasgow Airport spokesperson told the BBC that they were “bitterly disappointed”.
They commented: “We have been left in no doubt it is also a consequence of the Scottish government’s inability to introduce its proposed 50 per cent cut in air departure tax.
“[This is] despite clear and repeated warnings from both airports and airlines about the potential impact of this policy not being implemented.”
Ryanair carries over 130 million travellers from their 87 bases every year.
It comes ahead of warnings from Michael O’Leary that more strikes may affect Ryanair ahead of the Easter holidays.
He warned that he would “never agree” to some of the pilot union demands.
“We have some jurisdictions where we are getting…laughable demands,” O’Leary explained to The Sun.
“If we have to take strikes or disruptions in those jurisdictions, then we will take those.”
