DUB all airlines only 384 departures in the next 7 days! Anyone flying into DUB from UK or SA needs a negative Covid test taken within 72 hours of arrival. Arrive without a test and you can get a €2,500 fine or 6 months in prison. Soon other countries. Who is going to book? I've had 12 recent cancellations and await refunds / vouchers. Will I book for Spring / Summer? No way and perhaps others think that way.
Look at UK airports MAN next 7 days only 320 departures, STN 303 departures, GLA 119 deps, EDI 156 and of all those flights how many pax?
I don't think you'll see any FR flights from UK soon. Its how they will weather the storm.
