I have a later flight, and was going to try to fly standby on this one.

Seating map has 15 seats free, but, who knows...

Can anyone give me better insight, and if it's worth getting to the airport 3 hours early to try for the flight? My understanding is that if there's a seat available, they'll let me fly, regardless of fare class (ticket is booked as I, only Y is showing at this point).

Thanks!

David
