Not to mention that other factors clearly come into play across all of cost (air, fares, visas), time (travel), convenience (ticketing, visas, interest or in the location, security).
An xONEx ex-Pakistan is cheaper than Sri Lanka, but not by that much and for most people not by enough to be often warrant mention as a cheap location. Likewise ex-Gibraltar & ex-Sweden are considered cheap premium class starting points despite being notably more than say Sri Lanka or MRU.
