Heavy snow and subzero temperatures, which have gripped much of Europe, are causing moderate delays at airports across the former Yugoslavia today. A number of flights out of Belgrade and Pristina airports are experiencing delays, while Skopje Airport has seen some late departures this afternoon as well. On the other hand, Dubrovnik Airport, which saw severe winds disrupt a number of operations over the weekend, is operating normally today. Air Serbia has advised its passengers to arrive at least two hours prior to departure at Belgrade Airport due to the weather. "The airline continues to closely monitor the weather situation in Belgrade and advises air travellers to check airserbia.com for any updates to flight schedules. To avoid congestion at the ticket counters, the airline also advises guests to use its web check-in feature, which is available for all flights out of the Serbian capital", the company said in a statement. Heavy snow has also hit Istanbul, with Turkish Airlines cancelling more than 650 flights, affecting its operations to the former Yugoslavia as well.
