Great read - we too have booked a 10 day trip to Nepal/Bhutan for October 2008 - flying Emirates BHX/DBX/CCU and then into Nepal and on to Bhutan (no doubt Druk Air).
No F flights (only J on these legs with Emirates) but in the meantime looking forward to our Thai LHR/BKK in F (1A and 1K) for the New Year and sampling the new seats/airport/ground handling/lounge etc that Thai do so well.
Good travelling.
