Interesting reference to FlyBe reducing the number of flights to match demand. Yes, they need to do this, but there is a suspicion amongst regular pax that domestic flights leaving within two or three hours of each other are combined at very short notice. No airline can do this very often without alienating its most valuable customers, and leading them to conclude that rail/driving is a more reliable alternative. Whatever the reason, FlyMaybe has become a commonly used title.
As for Gatwick's landing fees it is easy to blame the airport's new owners, GIP. But the real blame needs to be put at the door of successive governments, who have failed to grasp the nettle of runway capacity at both Heathrow and Gatwick. With a single runway at their disposal, GIP are inevitably going to try to discourage the use of smaller aircraft, especially those with lower than average seat factors.
