I flew Manchester - Hong Kong via AMS this year with KLM. Overall was very impressed. Ticket price was good , all flights were punctual, and the gates at AMS were really close so even with 1hr 35 Min transit there was no rush. The aircraft AMS-HKG-AMS was a 747 Combi, nice enough but no seat back video, the overhead monitor near me was defective and the seat pitch felt rather tight (perception over reality maybe - don't know KLM's seat pitch).
But again, overall was impressed enough not to moan about it, which is good 'cause I hate flying...
