Irish holidaymakers are being warned to brace for some potential travel disruption this summer as Aer Lingus faces mounting pressures from an escalating fuel crises across Europe.
The airline has already confirmed the cancellation of more than 500 flights from it's summer schedule, around 2% of it's overall schedule, with tens of thousands of passengers affected.

While Aer Lingus has blamed the cuts on aircraft maintenance and schedule adjustments, industry experts say a worsening jet fuel situation could lead to further disruption in the coming months.
The concerns come amid a wider global energy crises linked to ongoing conflict in the Middle East, which has disrupted key oil supply routes as the International Energy Agency has warned that Europe could face a significant shortage of jet fuel within weeks.
The ongoing fuel crises has already been felt across Ireland which saw widespread disruption earlier this month due to nationwide protests over rising fuel costs.
Blockades at key fuel depots and the country's only oil refinery led to shortages at hundreds of petrol stations, underlining the fragility of supply chains.
Aer Lingus cancellations have affected a number pf popular routes from Dublin, Cork and Shannon, including flights to major European destinations such as Amsterdam, Athens and Berlin, as well as key UK routes like London Heathrow and Manchester.
The airline has said that the majority of affected passengers are being rebooked on alternative flights, often on the same day, in an effort to minimise disruption.

However, with demand for summer travel already high, availability on alternative services may become increasingly limited if further cancellations are introduced.
For now, airlines across Europe insist that immediate travel plans remain largely unaffected, with many having secured fuel supplies in advance.
However, experts warn that a prolonged crises could result in additional flight cancellations, increased airfares and fuel surcharges and reduced flight frequency on less profitable routes.
Passengers are being advised to keep a close eye on their bookings and consider travel insurance to protect against possible disruption.
