Initial thoughts are - Is it April 1st already?
Have they really done their homework on this? What size of market is there in the Carlisle area for a daily LTN service, can't be that much one would have thought. Road links to MAN from Preston and Lancaster are pretty good, plus you wouldn't really wanna go North to then come South again. Can't see many people coming across from the Newcastle area to take a flight from Carlisle. Likewise I would've thought that GLA & PIK were just as convenient for those North of the border.
Even with the supposed link into EZY routes, I can't see it being a roaring success, especially with a BAe146. Surely a smaller capacity turbo-prop would have been a better aircraft to start such a route with, even then I can't see it being viable.
