fluorescent, indeed it is a year since GO launched the STN route however they have never had a crew/aircraft base at Newcastle. This flight originates in STN, with STN crews and a STN based aircraft. So whichever way you like to look at the company, go/easy/goeasy neither have ever had a base.
The latest promotion is to publicise that EZY will now base two aircraft in NCL, and there will be crew employed at NCL to operate a route network originating from it - hence a new base.
