Flybmi are in bad shape. They have over-promised and underdelivered in many areas across their network. Without fundamental change, their future is limited and not bright.
Husky, from seeing their performance at LDY, to reading about details of their performance on other threads I think you hit the nail on the head. Over-committed. Using flaky equipment (it would seem). Doing work for other airlines and PSO, whilst not having the fleet/crew to do it. Shame, as their inflight service and overall experience is excellent.
