I "always" check in online too, but didn't get a chance to today--I wasn't at a computer. Ugh.
And so if delays are "advisory", shouldn't they stop bothering to send those flight status updates, since you still would, theoretically, need to arrive 30 minutes BEFORE the original departure time?

Since there was no Aircraft until about 40 minutes after the original departure time, how can a delay just be advisory? Again, I'm not mad--everything worked out--but I do recommend the online check-in!
