I thought the Air Berlin UK domestic flights were principally going to be used/marketed as feeder services to STN-Germany services? This doesn't seem to fit with domestic services into BOH although I believe Air Berlin do plan to launch more routes out of BOH besides PAD.
I would think its unlikely they would launch flights to GLA with the Ryanair competition to PIK. Flights to MAN and EDI could work, esp MAN.
Any ideas on further German destinations?
