UA does not show "A" class availability on their international flight on any CRS' site ie ITN or Travelocity. Each flight must be "requested on a NN basis" by the airline or travel agency booking that segment. If there are "A" seats, your flight will be booked immediately.
I book all my *A RTWs through my associate agency in Toronto, Canada.
