I agree manintheback, but the choice is yours of course. I generally will avoid flying "backwards" unless it's just a short one (BRU-FRA for example) with a good connection. I'll take a "sideways" (BRU-AMS), again with a decent connection. But, if I'm flying with the missus and I can save a total of 4000 Euros by taking a slight detour and still enjoy the comforts of C class then there's no contest. [That 4000 will buy me quite a few extra beers when I get there 5 hours behind you
