I love the smell of cigarette smoke on planes. Well, not the smoke, but the smell of the previous flight's smoke. If that makes any sense. Lufthansa economy class isn't all that amazing, although I'd take an A340 over a DC10 for comfort any day. NW have nevr deployed 747-400s on the Atlantic, it was 747-100s and -200s, and now more and more DC10s.
fly Saha Air 707s daily from Tehran's downtown Mehrabad to Mashhad, Kish Island and Ahwaz
