Yes well done Jet2 but
They are rather more exposed than the likes of Easyjet, Ryanair & baby, a number of their pax will be with Jet2hollidays.com and as such are classed as "inclusive" ie IT therefore the cost of continuing to keep them in hotels paying for their meals and still having to get them home will be mounting, i suspect that some of the Jet2.com pax will be on these flights as well, all in all a very expensive me thinks!
but well done and a good effort
Ryanair will offer comp: except
(in respect of any ‘Right to Compensation’) we can prove that the cancellation is caused by extraordinary circumstances which could not have been avoided even if all reasonable measures had been taken by Ryanair, including but not limited to political instability, safety and security reasons, weather disruption, labour disputes or failure or delay of air traffic control facilities.
If however you had flown with Ryanair see above!!
