Well this has now been reported on Cypriot TV (in PFO on hols). It would seem that the Cyprus Tourism Organisation have been involved in the said "new raft of flights" to PFO. They say Easyjet to fly to PFO from EDI twice a week. I certainly hope they do otherwise Ryanair will beat them to it. GSM always had very high loads so no reason why it wouldn't work.
The sooner Easyjet get one of the A320's here at EDI the better for good yielding routes like SSH, FNC, PFO, etc.
Wonder if this apparent new route to PFO will be announced by EZY?
