Prices have soared while flights stay grounded from Heathrow to Nice. In total 72 Heathrow-Nice flights on BA have been cancelled until July 15.

The airline had said earlier this week that destinations with multiple daily services were most likely to suffer a reduction in flights as the airline and airports grapple with staff shortages post-lockdown.

Other destinations hit are Dublin, Edinburgh and Amsterdam.

The situation is likely to get worse in coming days as aircraft refuellers are due to strike for 72 hours from 05:00 on July 21.
