Ryanair has reported a large rise in full-year profits.
The Irish carrier saw net profit for the year ending March 31 jump 66 per cent to €867 million, up from €523 million for the same period the previous year.
Ryanair said its ‘Always Getting Better’ passenger improvement programme had helped the airline attract “millions of new customers”.
"Our AGB programme is transforming our customer experience, our service, and the way we listen and respond to our customers," CEO Michael O'Leary said.
"We have won substantial traffic and share gains in all markets."
The programme introduced last year looked to reduce fees, extra carry-on luggage and allocated seating. It also targeted business passengers as it struck deals with GDS providers Sabre, Travelport and Amadeus.
Ryanair also saw passenger traffic increase 11 per cent to 90.6 million, which generated a 12 per cent increase in revenue.
To help with the growth in passenger numbers, the airline has ordered 183 B737-800 aircraft for delivery from 2014-2018, and 200 B737 Max 200's from 2019-2023.
The budget carrier renewed calls for airport expansion in the south east to be resolved swiftly.
In its annual results the airline said: "Ryanair strongly supports the development of additional runway capacity in the London market.
"We believe that the market should be free to develop three new runways, one each at Heathrow, Gatwick and Stansted which is the only long term solution to the capacity crisis in the South East, and which will encourage all three airports to deliver additional capacity quickly and cost efficiently."
