Sorry, my returning question:
Is there a chance to fly a 777 within Europe? One is 773 SQ MAN-MUC (and I do hope to test it someday). Anything more? In 2012, KE was flying MAD-AMS on 772, but the tickets were a bit more expensive (similarly for KE's VIE-ZRH on 744 in 2012).
As for 346... In 2012 I had a LHR-MAD booked (IB), but there was a replacement: 343 flew instead. It was a nice fligth anyway, my first flight on a 340. (The flight was apparently full in Y, yet, as you can see, a dozen or two of passengers were missing to make such a replacement impossible!) I hoped to have another try in some near future - but it seems that IB has withdrawn 346s from the route. So... not really likely to be able to have a European flight on a 346, huh?... (Does IB still fly 346s, and/or 343s, to the Canaries?)
PS. My second flight on a 343 was next day, MAD-FRA by LA. Also very nice (and also full in Y, of course part of the passengers were flying from SCL), with views of the Pyrenees and the Alps (BTW, I was wondering why the route was so much "bent" to the south; this was planned, because it was shown on the map on PTV - and it was great to see the mountains.)
