A threatened strike by fuel tanker drivers at Edinburgh airport is to go ahead with a warning of “widespread disruption” to festive flights.
The Unite union confirmed continuous strike action over 19 days in a dispute over pay.
The walkout is due to start at 5am on December 19 and continue until the early morning of January 6.

The union warned last week that employer North Air had to make an improved pay offer if strike action was to be avoided over Christmas and new year.
However, the company has refused to re-enter pay negotiations after the drivers rejected 4.5% pay offer following years of below inflation pay increases, according to the union.
Unite members “overwhelmingly” backed strike action in a drive to secure a better pay offer.
A number of key routes will be directly impacted by strike action as North Air is the only fuel supply company providing services to domestic and long-haul flights from Edinburgh airport.
Routes including United Airlines to New York and Emirates to Dubai along with Loganair’s domestic routes to the islands could be directly impacted.
However, Loganair chief operating officer Natalie Bush said: “Loganair plan to operate a full and uninterrupted service throughout the festive period.”
Unite industrial officer Carrie Binnie said: “Unite has had no option but to confirm imminent industrial action.
“North Air now has very limited time to resolve this dispute. The company’s belligerence is at serious risk of causing widespread travel disruption at Edinburgh airport over the festive season.”
A spokesperson for North Air said: “We are disappointed at Unite’s decision to proceed with industrial action at Edinburgh airport.
“We successfully concluded negotiations with Unite at six other sites ahead of the annual review this summer, which has seen colleagues across the business receive a 4.5% increase in pay – significantly above current levels of inflation.
“We remain open to discussion and are committed to working with all parties to minimise the impact of any strike action over the festive period.”
An Edinburgh airport spokesperson said contingency plans would be in place to minimise any risk of disruption.
They added: “We are disappointed that the two parties cannot reach a solution and urge them to continue discussions.
“We’re working with our airlines to understand their contingencies to minimise passenger disruption.”
