airberlin topbonus - Booking on Air Berlin?

Trying to get a flight STN-JFK for a friend August 2....ExpertFlyer lists availability on both Air Berlin and LTU, and for a rock bottom price, but when you go to book that route on AirBerlin.com the only dates available are April 22 - April 30?

Anyone know if I can book farther out? (I have an award ticket back to LHR for my friend the following week, but roundtrip isn't out of the question.) Thanks for any info!

They have obviously no longer loaded the through fares from STN. However, no problem to book two seperate tickets STN - DUS and DUS - JFK for 15 Euro plus tax, resp. 389 Euro plus tax.

Thanks!!!!!! Duh, where are my brains? I'll give that a shot and report back.
