I'm trying to use united.com's glorious award search engine and I've got 2 questions:

1.) Is there an abbreviation for all bay area airports, or some other way to search them all at once (as WAS does for IAD/DCA/BWI)
2.) Is it still the case that it will tell you there is nothing available on a given date if you've selected, say, morning, and there is an evening flight available (leads to requiring three searches for everyday... ugh)

As always, thanks.
