"encouraging" seems to be the official line eminating out of Jet2 and LBA.
AMS is doing well and forward bookings on the sunshine routes are reportedly strong. All achieved, so far at least, without the need to resort to 'free' seat offers or anything similar.
On the downside, the Bergamo route is apparently proving difficult to sell. With daily services there was always a danger that there would be too much capacity for a destination which is pretty much untried in the north and these uncertain times won't be helping. We should see their winter timetable fairly soon, which may reveal what's working and what isn't
On a slight aside, one noticeable area where Jet2 differ from the rest is that they have virtually no
PR / media presence. They have no 'front-man' to speak of and don't seem particularly interested in getting in front of the camera of in the papers to get a bit of free publicity. Even their web-site is devoid of any news or media relations section. Compared to their peers and competitors, very unusual indeed.
