Sounds to me like a bad day at the office that turned out ok in the end.
Out of curiosity (puzzled SLF here), would it not make have made more sense to divert to Manchester or Newcastle immediately as being Jet2 bases they can presumably better cater for diverted pax, or are there more parts to the equation than that? Do ATC have any influence over where an aircraft diverts?
Just some thoughts, I'm certainly not trying to make any controversial criticism, sounds like the flight crew handled it by the book
