LONDON, Sept 11 (Reuters) - Ryanair Group Chief

Executive Michael O'Leary warned on Thursday that the

Russia-Ukraine war would be an ongoing issue for all European

airlines for years to come, a day after Poland shot down

suspected Russian drones in its airspace.

"This is going to be an ongoing issue for all airlines and

all European citizens for the next number of years," he said

during the company's annual general meeting.

O'Leary said safety issues were discussed at a meeting of

the company's board of directors in the aftermath of the

incident on Wednesday, which marked the first time a member of

NATO is known to have fired shots during the war.

The incident impacted the airline group's on-time

performance on Wednesday, he added, saying it fell to 60% from

90% due to air traffic control issues.
