Some interesting wrinkles on Award Searches: If you want to re-do the search later, click on "Advanced Search" at the bottom, and the Award Flight Search form reappears. You can return to this at any time later, even after your session has expired, and click on Search to re-do. BUT If you are Platinum / 1K / GS and your session has expired, the re-do will not display the Saver Awards for Platinum Elites (ON, IN, XN), even though the little info box (on the yellow calendar display) does show your status correctly. You have to log in again to see these options. AND Even if you are logged in, the calendar does not highlight days where there are only xN awards available. An example of this, at the time of writing, is UA 927 FRA-SFO on 08-Apr-2012, which has one ON seat available.
