Djion
Dijon has been coming up on the live flight info ever since most of the peak summer routes started, at the same times as last year but it is always shown as cancelled, which probably means thats its been loaded onto the schedule as operating but Eastern must've decided to cancel it at the last minute presumably just before it could be loaded into their booking engine. Or somebody has just forgotten about it!
It does seem unusual for Eastern to not be operating it this year though as it apparently did well last year with loads mostly in the 20's (On a J41), plus it was extended and Eastern also said that the route would return for this year in April!
