Severe winter fog blanketed Václav Havel Airport Prague (PRG) for most of 15 December 2025, triggering the worst single-day punctuality drop of the season so far. Live statistics at 20:24 CET showed 73 % of departures delayed by an average of 50 minutes and 41 % of arrivals running more than 50 minutes late.
Meteorologists reported visibility at just 300 metres for much of the afternoon, forcing air-traffic controllers to widen separation minima. While no flights were cancelled, the knock-on effect rippled through evening wave banks, with British Airways, Jet2 and Ryanair services to London Heathrow, Birmingham and Naples all pushed back. Business travellers connecting onwards from European hubs faced missed meetings and hotel-rebooking costs.
Travellers who may need to re-route at short notice should also ensure their travel documents are in order; VisaHQ can arrange Czech visas and Schengen renewals in as little as 24 hours, sparing passengers the extra queue time that fog disruptions already impose. Its online platform (https://www.visahq.com/czech-republic/) lets corporate travel teams track applications in real time and upload digital paperwork, streamlining any emergency changes to itineraries.

Airport authorities said the delays underscore the urgency of Prague’s parallel-runway project, which will include CAT IIIb instrument-landing capability. Until that runway opens later this decade, capacity constraints during low-visibility operations remain a structural risk in winter months.
Corporate-travel managers should advise staff to build in longer layovers on PRG-originating itineraries from December to February and to use airlines’ mobile apps for real-time gate changes. Under EU Reg 261/2004, weather-related delays do not trigger cash compensation, but carriers must still provide meals and reasonable refreshments after two hours.
For cargo shippers, the fog created stacking at the Skyport freight terminal, delaying just-in-time components bound for BMW’s Dingolfing plant by up to five hours. Logistics teams may want to route critical consignments via Vienna or Leipzig until the weather stabilises.
