No AA sets them and by doing things like that they get to skew the numbers to make AA look uncompetitive to their Unionized workers.
So you think AA deliberately over-prices just to make you look uncompetitive? Or are they simply matching the prices set by the market. Yes, that concept that you hate to acknowledge when it comes to what the company wants to pay you, yet you think needs to be applied when it comes to what WN or UPS are earning this week...
In the example I discussed the guy was willing to pay what was needed to get to PHX and what he was willing to pay for was the part from NY to PHX, but AA showed most of the revenue as being driven on the first leg to NY which the guy would have driven if he could get the same price on the NY to PHX leg. In reality he bought the leg to New York to get the o legs from NY to PHX, the value was in the Ny to PHX leg. He could not just buy that leg of the trip, nor could someone who was in NY who wanted to make that part of the trip. However when AMR does their internal breakdowns of the numbers they show his ticket as an unprofitable one for AA, which they tell us about, and a very profitable one for the Eagle leg, which they dont really dive into.
Gee, Bob, you just discovered the first lesson in revenue management. Pricing isn't based on the flight segments you travel on. It's based on where you start, where you end, and how much the company thinks they can get you to pay based on years of experience.
Try to remember that the goal of pricing isn't to sell as many seats as you can, but instead is to charge the highest amount the market will bear. It's the exact opposite of employee pay, where the goal is to find the lowest hourly rate that most employees are willing to vote in....
In the real world, there's no such thing as taking a connecting fare and "only paying for what you use". This isn't wine by the glass or power by the hour.
Prices may not be set strictly by distance (they are for pass travel) but costs are broken down that way (one of your favorites CASMs)and thats how AA skews the numbers, in the end its all the same to AMR but tactics like this allow them to paint whatever picture they want to their labor unions. This little trick raises the CASMs and Lowers the RASMs for AA, which is then reported to the unions in PP slideshows through the graphs and charts that are impacted by those numbers.
They might be averaged by distance for analysis purposes, but unless something has changed, costs are not explicitly broken down by distance. My group developed the City Business Reviews which came out in 2005, and at least then, we never even tried to show a station or route specific CASM/RASM figure.
There are as many ways to show the fixed costs & local revenue at a station as there are ways to go fishing. If there's a lot of point to point traffic, you might be able just look at a couple factors, but when you're a network carrier, you also have to calculate an offset called "network contribution" so that when you're looking at stations who might not have a lot of point-to-point traffic, they get credit beyond just a distance based pro-rated value to help recognize the connecting revenue generated simply because you serve X city pairs beyond the hub(s).
I know. It's all smoke and mirrors, all made to confuse you and the unions into capitulation...
