I saw the banner for the cheap fall fares and the Bring a Friend for Free promotions this morning before work. I tried to search on a couple of different browsers, and the site wouldn't let me select any cities.
The same thing occurred 10 hours later after work. App seems to work fine, but using my big old desktop is so much easier. The point is, the site as a whole isn't working, not just for logging in.
I am surprised there hasn't been another upgrade announcement, since the last one went so well...
