As of a couple of months ago, they had filed for slots at GLA, but I haven't seen the slot listing post-handback so don't know if they are still planning this.
Having seen the load factors on some of their BHX routes (AGP/ALC OK, the rest
) I tend to agree with Shed-on-a-Pole that they may try to get their Midlands house in order before launching elsewhere.
That said, a reduction in the density of David Dickinson posters in the Birmingham area would be a service to humanity...
