What is your home city/country? How long is the trip to post from there, with what connections? How easy/difficult is it to travel to this city/country?
Midwest, United States. Travel takes a LONG time. At least 25-30 hours of total travel time with layovers in Seoul/Beijing/Narita, LA/DC. - Sep 2020
The US west coast. There are regular flights via Korea or Japan. Travel here is easy, and travel within the region is also easy. - Aug 2020
It is difficult and very time consuming to travel back to the U.S. Plan on an entire day of travel through limited connections. - Jul 2019
Where is home these days? Our home state is TX and it's a good 24-hour trip (plus or minus a few hours depending on connections) plus the additional excitement of crossing the international dateline. Pack that melatonin and caffeine. - Oct 2016
UK. Shortest is 12 hours with Aeroflot via Moscow. Although longer, I'd recommend to transfer through Seoul, or Beijing - it does pile on another 6 hours or so, but the choice of airlines is greater that way and it usually ends up more comfortable. Turkish Airlines offers connections via Istanbul, but the dead-of-night stop in Bishkek (with de-planing) is exhausting. - Feb 2015
Houston, Texas. 18 hours of flying with bad connections. - May 2012
Washington, D.C. is my home base. It takes at least 30 hours via plane from Ulaanbaatar to Washington Dulles. There are no direct flights from Mongolia to any part of the U.S. All flights go through Seoul, Beijing or Moscow. - Feb 2011
