Ryanair chief executive Michael O'Leary confirmed a normal schedule of commercial flights won't return until June 17.
The budget airline has grounded 90% of its flights, but will continue to operate on a limited schedule.
Until then, the airline is waiving the change fee for any flights booked up to the end of May, which can be changed to date up until the end of August.
A statement reads: "As most EU countries have imposed flight bans or other restrictions, over 90% of Ryanair's aircraft are grounded for the coming weeks.
"We will comply with these restrictions at all times. We are working with EU Governments to try to keep some minimum flight links open for emergency reasons, even though the passenger loads on these flights is very low.
"All the aircraft are disinfected daily. With low loads, social distancing is being optimised on-board. We ask all passengers to cooperate fully with our crews who are doing their best in difficult times to maintain vital links to/from Ireland and to/from the UK to facilitate our passengers and their families to deal with emergencies that may require urgent travel over the coming days and weeks.
"Ryanair apologises sincerely for the unprecedented grounding of our aircraft fleet, and any schedule disruptions this may have caused, but we must all work together with EU Governments to minimise the impact of Covid-19 on our citizens and our health services."
For those who have booked flights in the near future they will be given the choice to move their booking to another date before August 31st free of charge.
You will however have to pay any difference if you pick a more expensive flight - and you have to stay on the same route.
