Several planes have been flown the short distance from Prestwick to Glasgow International Airport during the COP26 summit.
In recent days flight tracking apps have recorded several aircraft making the 22 nautical mile journey from the Ayrshire coast.
On Tuesday, an aircraft believed to be Bolivia’s presidential plane landed at Glasgow International at 1:05pm, having taken off from Prestwick at 12:43pm, Glasgow Live reports.
According to flightradar24, there were five scheduled departures from Prestwick to Glasgow on Tuesday, including flights operated by FirstAir (for the Bolivian Airforce), Mauritania Airways and Cyprus Airways.
Reports of the flights have sparked outrage on social media, as world leaders and delegates meet in Glasgow in a bid to thrash out an agreed path forward for a global reduction in carbon emissions to avert a climate disaster.
One person said: "Dignitaries are arriving en masse in Glasgow by private jet for #cop26. Not only that, they are landing @ Glasgow then moving the planes to Prestwick after dropping off. The two airports are only 30 miles apart and the difference in road travel time to Glasgow city centre is 22 mins."
Another added: "They are flying planes from Glasgow International Airport to Glasgow Prestwick Airport, a distance of 38 miles by car... What a farce."

A further comment read: "Let’s not pretend that world leaders care about climate change when they are flying from Prestwick to Glasgow."
The UK Government, responsible for COP26 air traffic scheduling, have been contacted for comment.
