Very interesting reading.
My favourites (shorthaul);
A321 Mid-hauls on GLA-LHR services sitting in the CE section
767's in ET on domestics in the front cabin before the introduction of CE
2CD on the Embraer 190
My favourites (longhaul);
1A in CW on a three class 787
747 upperdeck in CW
Least favourites (shorthaul)
Any seat in an A319/320/321 other than row 1 or exit row due to lack of legroom
Least favourites (longhaul)
Definitely the 772 - I did an LHR-EZE in WTP and couldn't sleep. Similarly the return in the rear CW cabin was noisy and unpleasant.
