Thanks for clarifying everyone. I thought you were talking about the seat map in MMB. Sorry about the confusion.

I have re-read all your comments, and think I understand now. It seems though that the free version of EF is therefore pretty useless, cause it doesn't show seats sold, only allocated (as on MMB). And fare classes are anyway only available in the paid version.

Thanks for your patience with the EF noob!

Edit: I tried jackie's tip, and there is now a seat available.
