Jim,
I don't there is a need to disagree but there is a need to hear what each other is saying.
I DID NOT say that the LCC model has failed; I said it is failing at present to deliver the kind of margins that the network carriers are now delivering.
There are a number of reasons for that but fundamentally it says that the network carriers are able to better able to deliver revenue to cover their costs; part of that is the strong international environment, part is because fare increases have reached the limit of how much they can be increased, part is because the network carriers have increasingly been able to stand their ground in their strength markets - witnessed by the WN pullback in key US markets from PHL.
.
WN serves a smaller segment of the market, not a small market. The network carriers are the closest thing to trying to be a one size fits all air transportation system; sometimes that works, sometimes it doesn't. But market diversity and breadth can translate into revenue premiums and that is what the network airlines are trying to do - and based on recent performance are succeeding at doing.
.
Finally, while the notion remains that network carriers can't compete against low fare carriers, the evidence says that the network carriers have reached the point where they can effectively compete. The final pulldown of US at LAS started years ago so what happened in the past couple weeks isn't really indicative of the climate today.
While you want to point out that the low fare carriers continue to take domestic market share, that isn't entirely accurate. DL and UA each have about 25% of the domestic market; US and AA each split the other approximately 25% of the domestic market that is held by network carriers. The other half (give or take a few percentage points) is held by low fare carriers, of which WN is also close to 25%. So, on balance, if two network carriers each have twice the share of the single largest LFC and AA and US are both larger than the #2 LFC, then it would seem that the network carriers have better succeeded at creating nationwide systems than the low fare carriers have. Further, the network carriers control nearly all of the international market aside from some of the LFC Caribbean flying.
.
No one said the LFCs don't have a viable business model. But I also can't accept that the network carriers can't compete effectively against the low fare carriers.
The evidence overwhelmingly says that the industry is reaching a level of stability after 35 years; you did note that nearly AA carriers are reducing or stopping capacity growth in the year ahead - a huge accomplishment that was unthinkable just a few years ago - and possibly only because of consolidation on both the network and low fare carrier sides of the industry.
.
Finally, you know, Jim, that not many years ago the market capitalization of LUV was worth more than the entire network carrier segment of the industry. Today, DAL and LUV have been tracking pretty close together (as of right now LUV is worth about $100M more with UAL not far behind); Wall Street no longer sees the restructured network carriers as having failed business models or the network carriers as having models that can continue to generate the level of earnings they once did.
It is also notable that DAL and UAL have attained some level of market value parity with LUV but AMR (which hasn't restructured) and LCC have not - which also validates that size DOES matter in the industry; Parker continues to argue that US doesn't have it but needs it - and there is evidence that DL and UA are obtaining the intended benefits from their mergers.
.
While AMR and LCC need to continue to find the "sweet spot" for their business models, the same can be said for JBLU and RJET/F9 which are now assuming a much less significant role than it once did. But for carriers like DL, UA, and WN that have negotiated/are negotiating the changes in the industry, they are equally finding success with their respective business models.
.
It is not accurate any longer to talk of any particular segment of the industry being unsuccessful. The focus needs to shift to specific carriers and their strategies.
