Just giving guy in office grief about travelling MAN-LHR-DEN, but he seems to have got quite a good deal pricewise and the layover in LHR is minimal. However, when I tried to teach him the error of his ways, I was encouraged to find that Amadeus.net was showing MAN to PHL or JFK as the best option, albeit with 6hr+ layovers at the stop.
To MAN passengers, what difference does MAN-LHR-DEN as opposed to via JFK/PHL make? Still a transit hub on route.
Plus if it's BA as opposed to BD/UA then the experience at LHR will most likely be better than any US transit airport.
