Well, on Sunday we flew OGG-HNL on HA, and we asked if there was stand-by availability on an earlier flight right at check-in (at the skycap). I had checked the loads, and our flight looked fuller than any of the previous ones, but not oversold. Anyway, they offered us boarding passes for the earlier flight right at check-in. So, if I may generalize from this, HA seems to be the way to go if you want to stand-by. Unfortunately, however, this episode may be an exception to the rule. In the last few months, I've been firmly refused stand-by at the HA check-in counter in HNL, only to be added to the list at the gate... go figure? The only certainty now is that AQ won't allow free stand-by at OGG.
