Staff at Isle of Man Airport are expected to continue runway-clearing operations well into the night, with sub-zero temperatures forecast for the next few days.
A frost hardened snow overnight and the airport was shut for a time this morning, while sections of the runways were de-iced.
But although Ronaldsway is open for business, further snowfall brought some airports in the UK to a standstill.
Earlier, flights to Gatwick, Liverpool and Manchester were cancelled, and Flybe has since cancelled all its flights for the rest of today.
Airport director Anne Reynolds says it's proving an ongoing battle to keep things clear:
Plans submitted for 85 new homes on former Buchan School site
Reinstatement of home births 'remains at top of agenda' for Manx Care
New museum celebrates Island's 'long history of Freemasonry'
Weekend sailings at risk
