Dangerous? Not particularly. Difficult? Again, no especially once you've done it a few times, I got LHS after 18 months with no prior Airbus, command or Asia experience.
But it was UTTERLY exhausting. Low level cruise noise, delays, flying nights, earlies, lates, diverting and having to stay on the jet for another 6 hours at the whim of officials, 180 kts with 50nm to go, 60 min turnarounds in HKG with an aircraft change, ATC saying go slow, go fast, go away, cannot divert to nominated alternate, do an orbit in cruise, I could go on. Don't miss it a bit. You lot are welcome to do it and find out for yourselves, maybe its all fine now...
