Thanks, all, for your replies - much appreciated.
Price isn't an issue in the sense that I'm going for work, so I'm not paying, although, tragically, I will be going economy. I'll be flying on a Sunday in November (lucky, lucky me...) and essentially I'd like the least uncomfortable journey possible - and I regard free drinks on flights as a sine qua non of civilized travel!
It's looking like the most convenient option is via AMS on KLM - if anyone has any experience of that route/horror stories/tips, I'd love to hear them!
