Thanks guys for the thoughts! It did update to 72A and we're oversold by 5 (all LAX-SFO seems sold out today). I volunteered $300 on the app, but they still haven't called my name and started the bidding war at $400. Seems like they should've just taken my offer for $300....I'm cheap.
This is the most excitement I've had for a flight all year. This gate assignment was the first omen.
