Or sometimes you get so lucky, it's unlucky. Like the time I tried to go DEN-MSN memorial day weekend. Options were DEN-ORD-EAU, DEN-MSN, or another DEN-MSN. DEN-ORD and one of the DEN-MSN flights left the same time. DEN-ORD seemed really bad, so we tried DEN-MSN (which really wasn't any better). Would have gotten on DEN-ORD. The next DEN-MSN flight was 5 hours later, and booked to capacity (66/66). That plane had enough seats for me, the wife, the nonrev above us, and all nonrevs below us. And it still would have had an extra seat or two. Sadly, we gave up when we figured it would be 5 hours of waiting for nothing.
