Ryanair has said it is in talks with Boeing about adapting its aircraft so that some passengers could be placed in 'vertical seating'.
The low-cost carrier said it wants to get more people onto its aircraft by replacing traditional seating.
Ryanair spokesman Stephen McNamara said it was in discussions with Boeing 'in relation to adapt the aircraft to allow people to travel in vertical seating'.
'Passengers would not be fully standing, they would have something like a stool to lean on or to sit on,' he added.
Mr McNamara said Ryanair was looking into removing four rows, or 12 seats, of traditional seating on its planes to accommodate the standing room.
Chinese carrier Spring Airlines is in discussions with Airbus about a similar plan.
