First of all, does QR release more saver space to its own members than to its partners like AA, QF, CX, etc?

Second, what's the fastest way to find saver F&J space? I've been using aa.com until last year, when the results didn't match with QR site anymore. AA of course doesn't show 12 months ahead while some others do, with AA only 11 months ahead. I've been searching on QR site since, but the web site has full of bugs and takes several seconds minimum to move from this day to the following day.

Any 3rd party search engines recommendations? Pointsyeah didn't match with QR results, at least for ones 12mo ahead.
