I know that I'm bringing up an old thread but I thought I'd update people on what happened.
I'd accepted flying the 787-8 and was still keen to try out the product and then 48hrs before my flight, it returned to an A350 (as proven in my trip report: http://www.flyertalk.com/forum/trip-...t-doh-muc.html )
I felt incredibly fortunate as the following day was subbed to an A330!

Now to try and get on one of the early A350-1000 flights!
