Under Flight Availability you can search for specific flights:



Under the "Available Classes" column you'll see each selling class and the minimum number of seats that the airline is willing to sell in each class. In this case they are all zero.

I am not sure, however, if this feature is limited or restricted in the free edition of EF though.

Just as an FYI the date shown is US format as I am in the USA. I searched for 7th March.
