From the Manchester Evening News:
Full statement from Jet2
In response to local measures introduced throughout Spain to prevent the spread of COVID-19, including the closure of bars, restaurants, shops and activities including any water sports, we have taken the decision to cancel all flights to Mainland Spain, the Balearic Islands and the Canary Islands with immediate effect. We know these local measures will have a significant impact on our customers’ holidays, which is why we have taken this decision.
We are contacting our customers who are currently in these destinations, and who are due to travel, to advise them of their options, so we urge customers not to call us.
This is a fast-moving and complex situation and we are reviewing our programme as a matter of urgency, so that we can fly customers back to the UK.
The health and safety of our customers is our number one priority, and we would like to thank our customers for their understanding.
Understandable I suppose, but seems odd to do this while flights are in mid-air, rather than overnight??
