Airbus has suggested it could increase the width of aisle seats on its A320s by two inches, making them 20 inches wide, at the expense of the middle and window seats, which would each lose an inch making them just 17 inches wide.

The aircraft manufacturer evidently believes this could provide a solution for larger passengers who don't fit into a standard airline seat. At the moment, they have to book two seats, sometimes at higher cost.

However, a survey by flight comparison site Skyscanner found that 84% of passengers felt it was wrong that most passengers would have to squeeze into smaller seats as a result.

Of the 1,000 people who responded to the survey, the majority thought the idea was "ridiculous" and "unfair", said Skyscanner.

Airbus has not revealed which, if any, airlines will be installing the larger seats and what the likely cost to passengers might be.
