Profit after tax soared to €820 million in the three months to the end of June from €360 million in the same period a year earlier.

Passenger traffic rose 4% to almost 58 million and average air fares increased 21%.

Revenue grew 20% to €4.34 billion.

Ryanair said it also benefitted from the timing of Easter.

Chief executive Michael O’Leary noted that passenger growth will be constrained over the full year due to “heavily delayed Boeing deliveries”.

Ryanair “cautiously expects to recover almost all of last year’s 7% full-year fare decline, which should lead to reasonable net profit growth” in the full year, he added.

However, he warned that the outlook remains “heavily exposed” to risks including tariff wars, macroeconomic shocks and conflicts in the Middle East and Ukraine.
