I know this is a hard to answer question and I don't expect a definite answer, just a general idea about what my odds are. I'm planning to fly from Beijing to Europe in September 2014 (still a long time to go) and I'm considering going through Tehran on Iran Air to catch a flight on the 747SP. What are the odds that they'll still be doing that route in late 2014? I'd be fine with an equipment change for a 741 or 742, but would hate to find myself on an A340 or something. Do they swap equipment a lot on that route? Would it be a safer bet to book KUL-THR instead?
Thanks for your help!
