Ok, now do not all jump down my throat, but it seems to me a merger between one of these international pseudo-LCCs and a domestic LCC makes a lot of sense. It attempts to do what UA (and many of the other majors) are attempting to do, focus their assets on money making international routes, yet retain the domestic feeder structure for feeder traffic and to maintian a customer base (because you know that you can fly one airline/FF program to a lot of destinations).

Now consider a US LCC without the inflated costs (pensions) of most legacy carriers, a proven record of being profitable, and combine that with one of these pseudo-international LCCs. This would drive more business to the international carrier (feed + an established route structure that would allow people to remain on one airline/FF program) and the domestic fare structure could continue to operate as-is, and grow through by increased feed.

Like I said, makes sense to me, you may disagree... and I am sure many of you will.
