Proposed Vertical seating (source: www.ryanair.com)
A spokesman from Ryanair was reported to have said to the MailOnline that the seating would completely adhere to safety procedures. This strategy could lead Ryanair to increase seating capacity by 20% to 30% which could result in a good increase in revenues.
Ryanair does not seem to be the only airline considering this strategy. Chinese airline Spring has also put forward similar plans, estimating it could fit in up to 50% more passengers.
