I hope to fly from Beijing to Ulaan Baatar the last week of April. The only flights I have found were on China Air and the Mongolian airline, for over $500 US one way. I am wondering if anyone knows of a cheaper fare or another airline. Thanks for any information.
There are three airlines that operate between Beijing and UB. MIAT, the Mongolian Airlines, Air China (not china air) and Aeromongolia.
I am not sure that the latter actually lands in Beijing. I recall someone saying that they land someplace else and bus people to Beijing.
It is an expensive route to fly because there is little to no competition.

Thanks for the information. Ithought that was probably the situation. I think the train is my best option. Thanks again.

As of February 2008, an Air China roundtrip (not one-way) flight (Ulaanbaatar to Beijing) was $660 and MIAT is $420. I strongly recommend working with a travel agent, not trying to book this flight online. The travel agents have much better prices than the online services like Expedia. For example, where Expedia shows a $900 roundtrip on Air China, the travel agent can get it for $660.
Basically, you cannot access the cheapest Beijing to UB flights online. You need to use a local travel agent.
I recommend the following travel agencies for air tickets from Beijing to UB:
