The airline carried 17 million passengers in the first six months of its financial year, compared to 86 million in the same period in 2019 when it made a profit after tax of €1.15 billion.
The airline grounded 99% of its fleet from mid-March to the end of June, but managed a 72% load factor on flights it did operate.
Ryanair gave a bullish outlook despite the hit. It said: “We expect intra-European air travel capacity to remain subdued for the next few years. This will create opportunities for Ryanair to grow its network, and expand its fleet, to take advantage of lower-cost airport and aircraft opportunities that will inevitably arise.”
