LAX_LHR may have more info.
I am unsure of what exactly is happening with the whole TCX/DE 'merger' thing.
There are some cases where clear forward strides are being made, such as the codeshare arrangement, the BE 'hub' connections, a few long haul routes and lastly the basing of a Condor B757 at MAN this summer.
Then there are the signs that all is not so straight forward, such as looking for a route FTP to link long haul points such as DUB-CUN, the fact that despite them saying MAN will be the future 'hub going west', they are still launching routes such as FRA-MSP (Im not saying MAN-MSP would be more viable but if they are still opening these routes then what role is MAN supposed to take exactly).
Its just not a simple situation at all.
