Not sure if this is the right place to post this (my apologies if not), but I was hoping for some help / advice on what the best business class flight would be for going from LHR (London) to PVG (Shanghai) and back -- Nov. 6th going out and Nov. 12th returning (I'm somewhat flexible in that it can be a day later in both cases).

I'm normally a United flyer, but in this case it looks like it comes down to SAS, SWISS, Lufthansa, Qatar Airways (although this one is about 4 hours longer than the others), and Virgin Atlantic (although this one is about $2k more than the others but is non-stop unlike the others).

Any experience on any of those airlines going a similar route on the same plane?

Any preferences / suggestions?

Thanks!

Brian
