Jet2 started EMA-CDG in Summer 2014 originally but was cancelled in 2015.
It returned again only a month ago and was originally scheduled to operate right through Summer 2017 but the last flight is now today actually (23 April)... was hardly worth bringing it back at all in the end.
No idea why Jet2 brought it back unless there was a tie-in with holidays.
Eurodisney over Easter?
