JS: You are right, the taxes should have been backed out. At $138 of revenue:
RASM is $0.076
Op. Profit/ASM is -$0.04
Profit on the Ticket is -$72.24

You are correct in your reasoning... However, the other side of that argument is that if you fill a large number of seats at the loss-leading fare, you create three things:
1. The need to sell more "profitable" fares to make the flight break even or profitable... This means raising the "gouging" fare or selling more of the already high last-minute fares.
2. For every loss-leader you sell, you take away a seat to sell at a higher fare later.
3. You need to have a "profitable fare" that people will actually pay... Southwest has this... AirTran has this... The legacies largely don't, except where they compete with an LCC (and these are not profitable for the legacy).
Lastly, the industry has set an expectation now, where what was once the fare paid only by "incremental passengers" is now the fare that all passengers expect. Thus, the "incremental passengers" who were originally viewed as icing on the cake, since the seat would have otherwise been empty, have become "non-incremental".
Let's look at this another way...
For each $138 rt UAIR sells, they need to sell a $282rt fare in order to break even. (Break even would be $0.116*miles, or $209.50)... Now, we have to consider that UAIR will not sell 1 $282rt fare for every $138rt fare... Let's say its 2:1... That means for every two $138rt fare sold, they must sell 1 fare at $354 to break even... Of course, the problem is that the demand for the $354 ticket is not at a 2:1 ratio to the cheap ticket, yet the company needs the higher fare tickets...
So lets assume a 4:1 ratio... 4 tickets sold at $138rt, require 1 ticket at $498rt, just to breakeven... Of course, as the high end ticket price continues to rise, demand continues to fall... So as you continue to extrapolate this out, you can see where $2,000rt top-end fares come from... However the demand at that fare level is so small that it is very hard to capture... And given the ability for passengers to search the web for the lowest fare, perhaps even impossible to attain, ever again.
And note, we haven't even discussed profit yet.
Now to go back to your point, its better to lose $34 (really $72)/ticket than $210 on an empty seat... Yes that is true... However, that also suggests that if you cannot profit by serving the market, you should no longer be in that market...
