A British Airways flight was delayed due to a problem with a curtain dividing business class and economy.

The flight from Seville in Spain to London Gatwick was already late taking off due to fog and poor visibility, as the plane had to divert to a different airport on a previous journey.

When it finally arrived, passengers had to wait even longer due to the curtain problem and eventually they departed just over three hours late, at 1.45pm UK time when they had been due to leave at 10.30am.

People on board told how they were informed that there was a technical issue with the curtain, meaning they could not yet take off.

‘Passengers were very angry and suggested cutting off the curtain,’ one person told the Evening Standard from onboard the grounded plane.

‘I’ve never heard anything so ridiculous before as an excuse for a delay.

‘All the passengers were stuck in the boarding gate area with only limited food options. Wheelchair users were taken on the plane and then off again and then on again.’

The problem is believed to have been a safety issue, with part of the rail loose which could have caused a problem if it had not been secured.

A passenger called William posted on Twitter: ‘Sitting at Seville airport waiting for a delayed flight. Cause of delay…the curtain between business and euro traveller is broken. Really? Also absolutely no communication from the airport or BA staff’.

A BA spokesperson said: ‘We apologised to customers for the delay to their flight which was caused by the aircraft diverting to an alternative airport on its previous journey due to poor visibility. The aircraft has since departed from Seville.’
