I need to book two tickets on my travel date, currently I saw only 1 saver award available and it is on the partner airline (Air China). Just wondering how accurate the award ticket inventory at united.com is, especially it is for partner airline? If I make two reservations at roughly same time, will the partner airline's award inventory got updated right away so my second book will fail? I used to have success for cases like that on other airline's award booking (for example, hawaii airline), but never tried on united.com..
