Tenerife was served daily by Go, I'm not sure why they dropped the service, but Go didn't think it fitted well with their service model - and so the route was dropped after about five months.
I believe that Athens isnt a very successful route for EZY. I read somewhere that because the flight is about 4 hours and the airline makes more money from using its aircraft & crew on multiple sectors its a bit of a money drain with quite a lot of low yielding passengers.
So, who knows?
Are the Athens rumours true?
Would the bucket & spade brigade put up with next to no service on a 4 and a half hour flight?
