Ryanair has extended its limited schedule of flights to April 9th.
More than 90% of the airline's fleet has been grounded due to the coronavirus.
It is operating a number of limited flights for the next ten days for emergency reasons.
These flights will operate daily or weekly, the company said in a statement.
Ryanair says all of its aircraft are disinfected on a daily basis, while passengers are required to comply with social distancing guidelines on board.
A spokesperson said: "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 will be very low."
We're extending our limited flight schedule until 9 April - to maintain vital connectivity and emergency travel.

They added: "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."
Last week, the company said it is not expecting to operate flights in April or May as a result of the coronavirus outbreak.
In a letter to customers, Ryanair CEO Michael O'Leary said nobody can predict how long the shutdown will last but suggested the experience from China indicates it could take three months for the virus to be "contained and reduced".
