That is a tough one, because I know that I am palying less to go the same places this year then I did two years ago. While base fares may have increased, the fares people actually pay would be a much different thing to track. I suppose you could get a number by going to the airline's reports and dividing revenue passengers into the revenue to get the revenue per passenger, that's probably as good as indication as any, but it doesn't take distance or class inot the process. Because actual fares on real routes change so frequently, I don't think you can get a good number by comparing base ticket prices.
