I'm not sure today where Jet2 fits into the Lo Co spectrum. They were certainly a product of the Lo Co revolution, but with their 22kg baggage allowance and other frills perhaps they have crossed the line, in the same way that I wouldn't lump TUI in with the Lo Co.
Whatever, the only way I could see a Lo Co terminal working at BHX would have been to build a cheep passenger processing warehouse (terminal) on the Elmdon side, but that space has of course been taken by MAEL et al.
