Beyond a few superficial remarks, laughing off the stunt, the airline boss refused to answer questions about the protest, insisting he was in Belgium to discuss the issue of air traffic control.
“I love cream cakes,” O’Leary told reporters. “They’re my favourite.”
Farcical scenes took place next to a cardboard cutout of Commissioner Ursula von de Leyen, to whom the airline chief exec said he was there to present a petition of 1.5 million signatures “calling on the EU to protect all flights”.
Ryanair is Europe’s biggest airline by passenger numbers.
Climate activists have accused airlines of wanting to “have their cake and eat it” when it comes to emissions targets. Many countries in the EU bloc are now taking aim at short-haul budget flights over high per-passenger carbon emissions.
The Ryanair boss, who revels in publicity, appeared to enjoy the attention and the cake.
The airline’s Twitter account later shared: “Passengers are so happy with our routes and petition that they’re celebrating with cake”.
Ryanair pilots in Belgium have voted for strike action on September 14 and 15 over pay and working conditions. It is their fourth strike in four months.
