Ryanair on Tuesday said that its shareholders had approved a deal by the Irish no-frills airline to purchase 175 Boeing 737-800 aircraft worth $15.6 billion (11.7 billion euros) at list prices.
The Dublin-based carrier added in a brief statement that the aircraft would be delivered over a five-year period from 2014 to 2018. Ryanair had unveiled the deal back in March.
Tuesday's announcement came on the same day that British low-cost rival easyJet announced a mega deal to buy 135 Airbus single-aisle A320 passenger planes for $11.9 billion after agreeing big discounts.
EasyJet revealed the news amid the Paris Air Show, where European aircraft maker Airbus is battling for orders with US rival Boeing.
