Ryanair said it is extending its zero flight change fee for all customers who book before the end of March this year.
The airline also said it will now allow up to two booking date moves until October 31.
"In light of ever-changing Covid restrictions, Ryanair is giving customers greater peace of mind when booking their Easter and Summer 2021 holidays, when Ryanair believes air travel will re-open following the successful roll-out of the Covid vaccines in the UK, Denmark and many other EU states," the airline said.
Ryanair said its zero change fee promotion is applicable for bookings made after June 10, 2020.
Flight changes must take place at least seven days before the original scheduled departure dates to avail of the promotion, it added.
