Passengers hit by the air traffic control meltdown face being stranded abroad for up to a week, as it emerged that an incorrectly filed flight plan by a French airline may have triggered the outage.
Around 300,000 airline passengers have now been hit by flight cancellations since the hours-long failure of the Nats system on bank holiday Monday. The knock-on effect is set to last for several more days, as under-pressure airlines battle the backlog in a week where millions are already returning to the UK from their summer holidays.
