FYI, the sign up bonus for the no-fee card has been decreased to 5000 points after hitting minimum spend. However, on my flight home tonight, the flight attendants were pitching it and said that the 10k points offer was an inflight-only deal. I took an application out of curiosity (the application is a paper one, and you can only get the deal if you use the paper app). You can fill it out and hand the app back to the FA, or mail it in for the bonus. The app has stickers with the crew member's ID number on it, presumably for commission.
