Flight Problems

Aer Lingus at 5.1 per 100,000 faces flight problems as its top complaint category. As a smaller carrier operating transatlantic routes from Dublin, disruptions hit harder because rebooking options are limited — a cancelled Dublin-to-JFK flight may mean waiting a full day for the next departure.
