This sounds like the best of the lEA commercial department. Dwindling passenger figures so lease a jet in to do it because you have no staff to fly aircraft. Which is why you need the lease in the first place. But your passengers have deserted you because of the cancellations and lateness showing you are so unreliable. Hence vastly reduced revenue leading to a £3.3m loss. Best thing to do is to wet lease a jet.
The next ridiculous thing they'll think of is trying to do a codeshare arrangement with a major regional operator.
