An entire row on the new A350 has extra room in front as the seats are unable to be moved back. The plane is currently only flying short haul journeys, but cabin crew staff are now concerned as to what will happen when it’s used to go further afield.

Usual World Traveller Plus seats, BA’s premium economy, typically recline by 8″ and have a 31″ seat pitch. One stewardess said: ‘It’s obviously happened because they wanted to cram in as many seats as possible. We’ve been told that it was due to revenue that they’re like that. ‘No-one realised it was a problem until we started doing short haul on them. People kept asking if they were broken.’

Amy James, BA’s head of cabin crew, told colleagues in an internal memo: ‘It has been confirmed to me that there are six seats in row 35 where there are no recline.

‘These seats have however been given an additional inch of pitch so that they are 32″. ‘What I’m still investigating is what this means in terms of notification to customers and seating plans.’

Cabin crew staff say they have already have some issues with passengers being unable to recline the seats.

The new A350 has only been operating between London Heathrow and Madrid so far but will fly longer routes next month, including London to Dubai, Tel Aviv, Bangalore and Canada.

Only one aircraft is in circulation at the moment, but it is thought BA has ordered 18 planes, which are described as being like ‘posh hotel rooms in the sky’.They are also better for the environment, as they use a quarter less fuel and significantly reduce CO2 emissions.

The airline has admitted that six of their seats in the dedicated World Traveller cabin do not recline. A spokesman said: ‘Due to the layout of the cabin, a handful of World Traveller (economy) seats have limited recline. These seats offer more legroom to account for this.’
