Half-term holidays are at risk as airlines call off planned flights from the UK.
Earlier this week, EasyJet said it was cancelling a total of 240 over 10 days, over issues including air traffic control restrictions, runway works and airport handling delays. The airline had previously had to cancel 200 flights on Thursday due to an unrelated IT issue.
Meanwhile Tui said it had to cancel a "small number" of flights, due to operational and supply chain issues. There have also been reports of long queues and disruption at airports including Gatwick, Manchester, Stansted and Bristol getting in the way of many people's holidays.
