Air passengers travelling to and from Scotland have been affected by the snow and plunging temperatures on Friday, with dozens of flights cancelled, delayed or diverted - and one airport closing altogether.
A Met Office amber warning for snow is in place in parts of the country bringing road, rail and air traffic to a standstill.
In Tayside, Dundee Airport bosses closed its doors at around 10am on Friday due to the snow and ice, saying they hoped to reopen "once the weather has cleared".
Passengers flying into Glasgow Airport have already faced cancellations and diversions, with the 7.35am service from Dublin this morning landing instead in Edinburgh.
Since then Aer Lingus, British Airways, easyJet and Loganair have all cancelled flights to Glasgow, leaving holiday-makers and other travellers stranded.
A KLM flight from Amsterdam and a Ryanair plane from Krakow are the latest to be diverted to Edinburgh Airport, according to the live arrivals board in Glasgow.
Services departing Glasgow for London, Belfast, Dublin, Stornoway and other destinations have also announced cancellations or delays.
One couple returning from the Dominican Republic to Glasgow, via London Gatwick, told the Record: "British Airways have offered us a flight to Edinburgh this evening - but our car is in Glasgow at the airport car park.
"We’re thinking we might have to just book a hotel in London then fly up to Glasgow tomorrow instead, otherwise we have to make our way from Edinburgh to Glasgow anyway, which seems just as much hassle.
"We are still waiting on more advice. We may possibly get a flight from London City to Edinburgh at 6:10pm, then a taxi to get our car in Glasgow."
Glasgow Airport said work had been ongoing since midnight to clear runways and taxi areas, and advised passengers to check their flight status with the airlines themselves.
Meanwhile, drivers on Scotland's roads have also seen delays. A yellow alert was already in place, with warnings for motorists to take extra care this morning.
Traffic Scotland said wintry conditions were affecting the M73, M80, M90 and M8. The A9, A83 and A85 are also affected.
The Met Office said snow showers are moving across much of the country, with a number of road closures being reported in the early hours. The new 'amber' warning warning was issued at 3.53am this morning.
A spokesperson said: "Outbreaks of snow are expected to move eastwards across Scotland on Friday. Snow will initially fall to low levels, with 5 to 10 cm accumulating in places this morning in two to three hours.
"From late morning, snow at low levels will turn to sleet or rain, but further snow is likely above 200 metres where up to 20 cm may accumulate by afternoon."
Scottish Government minister Humza Yousaf warned people to take care during the "treacherous conditions", and advised people to check the Traffic Scotland website for updates.
Highland Council said the adverse weather meant some bin lorries were taken off the road. Rubbish in Badrallach wasn't collected on Thursday as a result, with the local authority pledging to collect bins "as soon as possible". People were told to leave their bins out for collection in the meantime.
On Friday morning, Stirling Council announced all its refuse collections had also been cancelled, and similarly asked people to leave their bins outside and they would be emptied as soon as possible.
