Arnold,
You make one basic error - equating an airport's "per passenger fees" to an airlines cost per passenger to operate there.
The first - an airport's cost per enplaned passenger - is the total paid by all airlines at that airport divided by the total enplaned passengers at that airport. Thus, this is the average cost per enplaned passenger for all airlines
The second - an airline's cost per enplaned passenger at an airport - is the total paid by that one airline at that airport divided by the passengers enplaned by that airline at that airport.
A hypothetical example - an airport which enplanes a total of 300,000 passengers with a cost per enplaned passenger of $12 served by only two airlines - $3.6 million paid by the two airlines combined.
- Airline A uses 16 of 20 available gates, and likewise 80% of ticket counter/ramp/baggage/etc space. It enplanes 200,000 passengers. It therefore pays 80% of that $3.6 million, or $2.88 million. Airline A has a cost per enplaned passenger of $14.40
- Airline B has an efficient operation, enplaning the other 100,000 passengers through the 20% of facilities it pays for. Paying only 20% of that $3.6 million, it's total bill is $720,000, which results in it's cost per enplaned passenger being only $7.20
While a bit of an extreme example, that is why you can't just use an airport's average cost per enplaned passenger to calculate a specific airline's cost to operate at that airport.
This is also the situation that US created at PIT - initially keeping all 50 A/B-con gates while cutting flights and thus enplaned passengers. It's cost stayed the same while being spread over fewer passengers, which drove US' cost per enplaned passenger up compared to other airlines at PIT. The situation today is only somewhat better - US is keeping 10 gates/ramp space/counter space/baggage space to handle only about twice as many passengers as WN does with 3 gates - resulting in US' cost per enplaned passenger being higher than WN's.

Southwest Cuts Growth Plans Again

Southwest Cuts Growth Plans for Second Time; Expects 4-5 Percent in 2008
DALLAS (AP) -- Southwest Airlines Co. said Tuesday it would slow its planned growth in 2008, the second time this year that the low-cost carrier has reined in expansion as it struggles with high fuel costs.

The airline said it would grow 4 percent to 5 percent next year, compared with earlier expectations of 6 percent in 2008. The company will retire planes faster than it adds new ones in a bid to boost profits.
"We are concerned about growing evidence of slowing economic growth that would inevitably affect passenger demand, coupled with a surge in energy prices," Chief Executive Gary C. Kelly said in a statement.
Southwest's announcement came a day after rival Continental Airlines Inc. cut its growth expectations for next year to between 2 percent and 3 percent, down from 3 percent to 4 percent.
Dallas-based Southwest also reported Tuesday that November traffic grew 2.6 percent, measured by miles flown by paying passengers. That growth, however, failed to keep up with a 6.4 percent increase in capacity.
As a result, average occupancy on Southwest flights slipped to 69.3 percent from 71.8 percent in November 2006.
The airline plans to add five to 10 new planes next year, down from its previous plans for 19 Boeing 737s. Chief Financial Officer Laura Wright said the airline would also retire more older jets than previously planned.
Southwest first cut its growth plans from 8 percent to 6 percent in June, and Kelly hinted in November at further tightening.
Southwest has options to buy fuel at below-market rates, which gives it an advantage over its rivals. Still, rising fuel costs are making it harder for the airline to hit its financial goals.
In addition, Wright told investors in New York that nonfuel costs will also rise next year, citing higher maintenance needs.
The airline is also in negotiations with pilots for a new contract that could lead to higher labor costs.
Southwest is trying to offset higher costs by generating more revenue from ticket sales to business travelers. It recently began offering business travelers extra perks, such as early boarding and a drink for a slightly higher fare.
Southwest shares rose a penny to $13.74 in morning trading.
