As the thread starter - I flew back to Oz from Berlin, Qatar Business Class, it was the old BC, and OK. Not really the 10 star utopia suggested on TV ads but an order of magnitude in front of 10 abreast economy.
Seeing the barrage of CNN etc continuous loop TV presentations, in various hotels, about Qatar's new business class, now with a bunch of aft facing seats made me think - haven't we been here before without a great deal of success?
