Thanks for the links. I'm trying CPH - LHR - JFK - (via PHX to) - SFO - LHR - CPH, but of course the JFK - PHX - SFO isn't available at the moment, and the CPH sale ends in a few days. It's available for the month before I want for £1,475 in I / P.

However, having looked at the open Jaw CPH - LHR - JFK (...) SFO - LHR - CPH in J (I class) it costs £1,073 and the JFK - PHX - SFO in F (P class) for next June it's £441 - a total of £1,514.

Maybe for the extra £39 per person I should book the BA flights now and the AA flights later, or alternatively leave the whole thing to later in the year when another sale will, no doubt, come along.....
