I'm looking at flights between NYC and Tokyo. When I search Kayak, there are a ton of Air Canada flights. But when I search United.com, none of them show up. Did something change? I've booked Air Canada flights on United before. On a related note, I want to book on United so that the trip will apply to my United account. I believe the only way to get credit for PQM/PQS/PQD is to book directly through United. Just to be sure, am I right or am I missing another way?
