Hey everyone, just spotted this thread and was really happy to see all the comments about Google Flights. Though I've been at Google for nearly 9 years, I'm pretty new to the Flights team, so there's still a lot I'm learning... but I'll try to tackle at least few questions below :)

(I'm also both an oldtimer and newtimer to HN; long time lurker, and I opened an account ages ago, but sorry I've not been active here before!)
