Really depends what time your flight departs and whether the flight is timed to depart with other mainland bound flights. Yesterday, I made it to the airport at 5:15, got my boarding passes (standby), got through security, and made a 5:49 flight. I don't recommend this... But just showing it's doable at certain times of the day. If this were mid afternoon, forget about it.
