i'm trying to get my parents to AVL from IAH over christmas using my many UA miles. the exact dates i want are currently not available on ua.com with a saver award, although standard awards are available. two questions: 1. i know i can book a saver award for dates that are available and waitlist for the dates i want if it's me flying, but does it matter that i'm not one of the people traveling? can i waitlist for two other travelers? 2. does this work with *a inventory, or does it have to be UA metal? CO has a nonstop IAH-AVL, while if we stick to UA they'll have to go through ORD...always tricky in december, especially for non-frequent travelers. thanks!
