Thanks. It turns out I waited a little too long to try to change those tickets (beyond the 24hrs) and the change fee went up to $125 per ticket. So, I'm still leaving Friday night. I'll be there for the fireworks, though, since the flight doesn't leave until midnight.
I plan to head to the airport around 10 PM. Is that too much time for a midnight flight or just right? Here in Anchorage I usually don't arrive at the airport until at most 90 mins prior. Faster security lines for those of us who are MVP Golds
