spinchange, thanks for the love!

Short answer re price discrepancies: it's complicated. It's absolutely in our interest and the airlines' interest to get pricing 100% right, and we do work really hard to eval and improve on this.

One situation that can happen is that an airline has, say, 3 seats remaining at one fare and 1 seat remaining at a cheaper fare; when you selected the flights or immediately before, that 1 seat was still available, but by the time you click through, it's not, so you get the pricing for the fare with 3 seats left.

One of the things that's amazed me in my flights education after joining the team is just how super-dynamic pricing is.

No, to my knowledge it's not based on your referrer or cookies or anything like that ;). I'm just talking -- person-independent -- pricing from hour to hour.

On a related note, I used to think that airline pricing was pretty capricious and random; now I realize that the airlines hire some of the smartest folks to develop pricing strategies, and nothing is left to chance ;).
