Well I've had a e-mail this morning cancelling my EDI -ACE flight in September, and I see its looking like they have cancelled their EDI departures for the rest of the year.
To quote the e-mail,
"We're sorry that due to the unprecedented coronavirus (COVID-19) outbreak your holiday is no longer going ahead as we are operating a reduced flying programme this summer. Please see below for your affected booking(s)."
Thats the second Jet2 cancellation for me this year
