Best times/days to check award inventory?
Anyone have any thoughts on when are good times/days to call and check with UA for MP award seats? I have a *A itinerary and can't waitlist for C seats on one UA metal segment (NRT-HNL), so I'm parked in e+ and hoping two C seats open up.
Searched the forum but couldn't find anything definitive... may be the case that there is no magic time/window for calling, but things change, so who knows. Thanks!
