Thank you IMH. Am I correct in thinking that the LH business seat isn't horizontal? I've no experience of LH. Can't decide whether to go via EWR or try and find something straight through to LHR or FRA. Would prefer to get the overnight slog over and done in one go without a stop on the easy coast.

Edit: and thank you msmorley. My ideal was to get a horizontal bed for the longest possible sector, ie west coast to one of the European hubs. I'm actually aiming for GLA, so assumed that UA or LH to FRA would be the best choice. If LX were in the running, however... hmmm. Will have some thinking to do.
