On the *A MegaDo we got to roam through a brand new LH A340. (The bathrooms are downstairs so this way they can fit more seats on the main deck. It's a rather interesting config.) The seats still have ashtrays in the armrests. Someone asked about this, as obviously all LH flights are non-smoking now. We were told that in case someone decides to light up, there's an ashtray where it can be safely extinguished. (Undoubtedly after a strongly worded scolding from the FA &/or Captain.)

But now that this thread has been bumped, does anyone know of any commercial carriers that still allow smoking onboard? I'd be surprised if any are left.
