Catie and Phil Allen should have been enjoying their first holiday in two-and-a-half years. Instead, they are at home ringing round for refunds that won't be paid. The couple are among the many thousands of air passengers caught up in the chaos caused by the four-hour shutdown of the UK's air traffic control system on Tuesday. It means their holiday to Slovenia has been cancelled and - although their flight was refunded by British Airways - they estimate being left £1,300 out of pocket from unused accommodation and excursions. It's not the first time - and won't be the last - when passengers are left flying on a wing and a prayer after problems at UK airports. So, here is how their case relates to others, and why they have taken such a big hit.

Image caption, Zelensky's plane after it landed in Norway after flying in from Moldova A plane carrying Ukrainian President Volodymyr Zelensky was delayed by a Russian drone as he prepared to fly to attend a state funeral in Oslo, Moldovan and Norwegian authorities say. Zelensky and his wife Olena were on the jet at Chisinau, Moldova's capital, ahead of Wednesday's funeral of Norway's King Harald V when the unmanned aircraft crossed over the Moldovan border. The drone prompted an immediate airspace shutdown and Zelensky's plane was left on the runway for around an hour before it could take off. The flight was only authorised after it was confirmed the drone had come down 160km (100 miles) away. Asked by reporters on Thursday, the Kremlin said there had been no threat to the jet. Zelensky's plane had been due to take off at around 16:30 (14:30 GMT) from Chisinau International Airport.

Dmitry Artyukhov, the governor of the Yamalo-Nenets Autonomous Okrug region, wrote on Telegram that the drone attacks had been intercepted and "debris from the drone caused a fire upon impact". There have been no reports of deaths or injuries.
