Sorry bud, but the data that you gave does not indicate a 79.3% ldf. In fact, with the data that you gave, you cannot determine the ldf for

WN in

DEN. In the industry, most airlines (if not all) do not measure the load factor as the number of passengers divided by the number of seats because you have flights off all different lengths. This will cause a discrepency when trying to measure all routes in a market or in a system. Airlines calculate their ldfs as a fraction of rpms - revenue passenger miles (or rpkms) and asms - available seat miles (or asms). This way, you have a means of getting a standardized load factor across all routes regardless of length. This way, longhaul flights - which are generally a greater source of revenue - get represented on a standard scale with shorthaul flights that operate more frequently and tend to generate less revenue.

Because of this, we cannot tell what

WN's LDF from

DEN is for sure. Based up my knowledge of the situation, I would imagine the

WN's LDF from

DEN is less than the 79.3% that was stated, but still comfortably above the 68.5% for the system. Overall, I would say that they are still doing well in

DEN, I just wanted to point out the correct way for calculating LDF and how much it can change without further knowledge of the number of pax travelling to each destniation from

DEN (or any other given city).

Take a look at the cities that

WN flies to from

DEN:

DEN-

LAS - 615 miles

ASMS per flight= 84255 (137*615)

6 flights daily in March

Total weekly seats = 5754

Total weekly ASMs = 3538710

DEN-

PHX - 590 miles

ASMS per flight= 80830 (137*590)

5 flights daily in March

Total weekly seats = 4795

Total weekly ASMs = 2829050

DEN-

MDW - 907 miles

ASMS per flight= 124259 (137*907)

4 flights daily in March

Total weekly seats = 3836

Total weekly ASMs = 3479252

DEN-

OAK - 943 miles

ASMS per flight= 129191 (137*943)

1 flight weekly in March

Total weekly seats = 137

Total weekly ASMs = 129191

DEN-

SAN - 839 miles

ASMS per flight= 114943 (137*839)

1 flight weekly in March

Total weekly seats = 137

Total weekly ASMs = 114943

DEN-

BWI - 1500 miles

ASMS per flight= 205500 (137*1500)

1 filght daily in March

Total weekly seats = 959

Total weekly ASMs = 1438500

Total Seats per week = 15618

Total ASMs = 11529646

BWI - 6.14% of seats - 12.48% of ASMs

LAS - 36.84% of seats - 30.69% of ASMs

MDW - 24.56% of seats - 30.18% of ASMs

OAK - 0.88% of seats - 1.12% of ASMs

PHX - 30.70% of seats - 24.54% of ASMs

SAN - 0.88% of seats - 1.00% of ASMs

As you can see, the percentages that each market accounts for can vary by quite a bit. Chances are, there was not an equal number of passengers on each flight. The market ldf depends upon what the distribution is of passengers between the different flights. For instance, if more people flew on each

LAS and

PHX flight, and these flights accounted for a larger portion of the total pax, then the LDF will be less than the 79.3% value that was calculated. If the flights to

BWI and

MDW generally carried more pax per plane than the

LAS and

PHX flights, then the LDF will be higher than the 79.3% value that you calculated.

Let's say that the

PHX and

LAS flights went out full for a week and the remaining flights took and equal share of the remaining pax (probably unlikely, but used for an example here). In a week at 79.3%, that would be 12385 pax. So, 10549 pax were on the

PHX and

LAS flights, leaving us with 1836 pax. Let's say that the

SAN and

OAK flights also went out full, leaving us with 1562 pax. Let's then split the remaining pax to be 1500 to

MDW and 62 to

BWI. Again, these results are highly unlikely, but I am just showing them as an example of how the numbers can change.

So, our RPMS would be 93000 (

BWI) + 3538710 (

LAS) + 1360500 (

MDW) + 129191 (

OAK) + 2829050 (

PHX) + 114943 (

SAN) = 8065394. Thus, our LDF would be 8065394/11529646 = 69.95% (could be lower if we had all pax going to

OAK and

BWI go to

MDW instead).

Conversely, suppose that

BWI,

MDW,

OAK, and

SAN went out full. This would leave 7316 pax. Suppose that we split these equally between

PHX and

LAS.

So, our RPMs would be 1438500 (

BWI) + 2249670 (

LAS) + 3479252 (

MDW) _ 129191 (

OAK) + 2158220 (

PHX) + 114943 (

SAN) = 9569776. Thus, the LDF would be 83.00%

As you can see, the actual LDF will vary depending upon the distribution of the passengers on each flight. Take a look at the link you posted for

WN's Feb ldf. The value of 68.5% is calculated by dividing the rpms by the asms.

Hope that this was helpful in clarifying that. I'm willing to be that during this time, someone put a simplified and easier to read version of this up already!
