Our QF11 on March 31 has changed to the old configuration. Our nice seats upstairs in Y, carefully selected after endless examination of this thread, have disappeared. Sniff. Now locked out of seat selection on the Q web site. Complicated by the fact that SWMBO is on same flight on different booking and is only silver.
Am traveling on the same flight and had pre purchased 35 j/k upstairs. Called qantas after the change of aircraft and they happily allocated 66 D/E as an alternative.
