Have just tried including LHR-DXB in an AONE3. In the past, no problem finding A class availability. Since it now has to be booked into F class, I thought, goodie, more availability. NO! Nearly all the 388s I entered in ExpertFlyer showed as available in F in April and May next, but when entering them in the Oneworld tool, only a handful showed as available. The 777s on the same route for the daytime flight are still plentiful.

i sense more restrictions to the RTW F tickets in the future.
