This will always be true for US due to its network dynamics. There are a lot of shorthaul east coast flights with small gauge equipment. This is usually compensated by generally higher RASM on short haul vs long haul. However the RASM growth was overshadowed by CASM skyrocketing to oil.
Is the CASM high yes but in proportion to RASM it does ok. Always look at the whole picture not just one metric.
Almost complete hogwash, sir.
Comparing US to other carriers takes oil out of the picture.
Please check stage-lengths compared to, oh, say, SWA and see how that cripples your argument.
One reason CASM is still so high is because the labor groups allowed management to offset labor savings by extracting more of the cash flow to creditors, drunks, family kin that can't get jobs elsewhere, etc. I mean, who benefits when our stellar management team picks $24 million crippled RJs over $6 million zero-timed airframe, completely refurbished and fully certificated DC-9s?
Almost entirely labor's (ALPA, CWA, AFA, etc.) and, of course, the employees making up those groups, fault for allowing these thieves to operate like this. It is like the people making up White House policy. They are hardly Republican, much less conservative. Simply put, they are thieves and thugs hiding behind what was once a grand ideology. Same with the airline industry. Too much money too easily hidden by accounting rules set up to thwart transparency.
Time for a union that refuses to play "hide the salami" with management.
