Major UK airline Aer Lingus has cut more than 500 flights from its upcoming schedule, according to reports.

The ongoing conflict in the Middle East between the US, Israel, and Iran has resulted in a recent spike in fuel prices.

Several major airlines have already responded to this spike by increasing fares, adding or increasing fuel surcharges, and cutting flights.
