I'm looking at an intl J award on US metal that currently has 1 seat available. I need two seats. I know there is a lot of unpredictability with regard to whether expired holds go back into award inventory etc. but I'm interested in trends. With US Airways, is it generally a good idea to place an award hold on the first seat and see if another seat appears, or just wait and see if 2 seats appear together and risk that the first seat gets snatched up in the meantime?

I have the miles in my account to book immediately, but am not willing to risk paying the redeposit fee if I book one seat and another never materializes. Just wondering what my optimal strategy is given others experiences. Thanks!
