Ryanair group chief executive Michael O'Leary said the low cost airline's flights are filling up very strongly for June, July and August with fares at their lowest ever summer levels.

"Fares have been lower than they have ever been before because we don't have the normal advanced bookings already in the system for June, July and August," Michael O'Leary told Sky News in an interview.

"People who have been locked up in Britain and Ireland are bursting to go on holidays," he added.

Earlier, Ryanair said it carried a total of 1.8 million passengers in May of this year, up from 0.07 million the same time last year when tight Covid-19 lockdowns were in operation.

The airline said it operated over 12,000 flights in May and it reported a load factor of 79% on these flights.

It said its passenger numbers so far this year are down 75% on the same time last year.
