There you are. So Doug doesn't know the numbers as well as you.
As they say - it's all in how you spin the numbers, so you decide. Here's the CASM figures for each airline each quarter starting before BK2 for US through the first year after a single certificate was issued and only combined numbers were reported to the BTS. These are system numbers which includes Express which is why they don't agree with what's reported in the quarterly reports for mainline.
2Q04 US = 16.8 cents, HP = 08.3 cents
3Q04 US = 16.1 cents, HP = 08.5 cents
4Q04 US = 15.0 cents, HP = 08.6 cents
1Q05 US = 14.8 cents, HP = 09.7 cents
2Q05 US = 15.3 cents, HP = 11.4 cents
3Q05 US = 16.3 cents, HP = 12.2 cents
4Q05 US = 17.8 cents, HP = 13.4 cents
1Q06 US = 18.8 cents, HP = 11.3 cents
2Q06 US = 17.0 cents, HP = 12.7 cents
3Q06 US = 15.7 cents, HP = 14.1 cents
4Q06 US = 15.4 cents, HP = 13.6 cents
1Q07 US = 15.9 cents, HP = 12.1 cents
2Q07 US = 16.3 cents, HP = 13.1 cents
3Q07 US = 15.8 cents
4Q07 US = 16.4 cents
1Q08 US = 17.0 cents
2Q08 US = 20.1 cents
As you can see, HP consistly had lower CASM and some quarters substantially lower CASM pre-merger agreement. So if you can explain how you can buy two shirts at different stores, one costing $25 and the other costing $35, and have the average price of the two end up being $25 you'll have your explaination of how Doug was right. Otherwise he was spinning like a top.
Tell me again what about the merger with US has made the cost of flying a west A320 from say PHX to SAN increase?
Assuming it's flown with west metal and crews, and omitting outside factors that have affected cost (like fuel, parts, rent, landing fees, etc) the cost wouldn't increase (omitting any affect from other workgroups since I have no idea what affect combined contracts had on their compensation). What has happened is that the CASM of the airline increased (that averaging a low number with a higher number thingy) so revenue has to increase to cover those higher costs which means RASM must increase which means yield must increase. The NE is more of a business market (plus some other routes) which means that yields tend to be higher there while many of the lower yield routes (like to/from LAS) don't produce enough yield to support the higher than HP alone CASM. In other words, parts of the HP system dodn't produce a high enough RASM to support the combined US CASM even though it supported the HP CASM.
