British Airways has confirmed it is to axe 10,300 more flights from August to the end of October.

The cancellations will be mostly  from London Heathrow, London Gatwick and London City airports.

They will mostly be domestic and short-haul flights.

The Independent newspaper estimates that ‘at least’ a million customers will already be booked on the cancelled flights.

BA has announced the cancellations ahead of Friday’s deadline for airlines to temporarily hand back take-off and landing slots they aren’t sure they’re going to be able to use this summer.

If they hand the slots back before Friday, they won’t lose them under an amnesty announced by the Department for Transport to try to encourage airlines to cancel flights now rather than wait till the last minute.

Announcing the latest cancellations, BA said: “The whole aviation industry continues to face into significant challenges and we’re completely focused on building resilience into our operation to give customers the certainty they deserve.”

Including the flights cancelled last month, BA has axed nearly 30,000 flights this summer, which is around 18% of its planned schedule, according to The Independent.

Long haul flights are unaffected by the latest cuts.
