People who travel frequently by air may have a good idea of the ongoing trend in the world of airfares. Airfares vary depending on the type of travel. The destination and the standard of amenities that are provided by the airlines also make a lot of difference. For instance, if a travel is to a far off destination, then it would translate into an increase in the airfares. Similarly, a travel by First or Business class would obviously cost more as compared to economy class.

Airfares need not be uniform everywhere. In most cases, it is observed that airfares differ extremely from one country to another. The reasons of this price discrepancy are attributed to the fact that factors like exchange rates, student pricing, bilateral agreements between countries, and the dynamic elements of the market like competition and competence differ from country to country. For instance, the price of an international economy-class round-the-world ticket with the Oneworld airline alliance is around $3,900 from New York, $2,565 from London, $2,640 from Paris and $3,111 from Bangkok. This price difference is directly related to the market situation and the economic condition of a particular country. Some times, these discrepancies may also arise due to the 'brand' factor. Lufthansa is the cheapest European airline. Hence, many students or economy class people may favor traveling by Lufthansa since the airfare will be the cheapest as compared to the other carriers of European origin.
