Total cost estimate does not include cost of travel from where you are now to the first city, nor does it include cost of travel from the last city to an external destination.

Estimates are based on currently available data which may lag behind reality. Information is provided with no warrenties real or implied. Possession of this list or literature does not constitute an offer nor an intent to sell.

This site is provided for educational and introspective purposes. We do not recommend nor endorse travel to any particular city, including those which may be in active warzones or within the bounds of diplomatic embargoes. The reality is that all cities exist. We cannot pretend that they don't exist. We should be aware of things that exist lest we fall into state-sponsored erasure of people and history.
