Glad you didn't get the errors...

As for the missing lock, it's probably because you're within the Store's frameset: http://www.flyertalk.com/storefr.shtml

The problem with framesets is that most browsers show the lock if the overall frameset is secure, and don't display it if not. So, even though the page that you're actually ordering through is secure, since it's within our FT frameset, you don't get the lock.

It's an unfortunate side-effect of using frames and we'll probably be moving away from that when we move FT over soon.

If you're not certain about the security of the page when you get to your CC info page, right-click (or CTRL-click on Macs) and select to have the page open in a new window. You should see something like:
