I don't se it as a monopoly there will be 4 major carriers and several others that are close to major them selves. They are also competing on a world stage with many other airlines.
You're right; it won't be a monopoly, but those four major carriers carry 90% of the domestic passengers, which is fairly high market concentration.
Now my power company? there's a monopoly they have a product I have to have and they are the only game in town.
Flying is at least an option.
Sure, that's why most states have a utility regulatory agency that sets consumer rates. The power companies have to ask for permission to raise rates and the agency puts on a good show before approving the higher rates.
Electricity is something you "have to have?" I admit that it's something we've grown used to having, but "have to have?" There are Amish people in parts of the country whose homes are not connected to the power grid. Not how I choose to live - but electricity is very useful, but not required. Besides, you have options - put up some PV cells on your roof and let the sun supply your energy. Construct a windmill or water wheel.
If the DOJ was gong to sing this song they should have done it a couple of mergers ago.
There is nothing in antitrust law that supports "the government blew it in prior mergers by not stopping those companies from merging and thus, we have an absolute right to merge." A lot of people have said that in the past couple of days, but that ain't the law. That's tantamount to saying "The nation's consumers will pay the price for previous government failures to enforce the antitrust laws." That's an absurd result and the federal government doesn't have to let consumers twist in the wind just because previous administrations failed to enforce the law when it had the chance.
After each of those prior mergers, there were more large major airlines than there will be after this proposed merger. Following the UA/CO merger, there were five large major airlines remaining. A cogent argument can be made that five was sufficient competition and that four is too concentrated a market.
I fully understand why a lot of US Airways employees are very angry at Tuesday's lawsuit and why many of them want the merger to occur. For US pilots, it appears to be the easy way to escape their very low hourly payrates and finally get payrates that are in the ballpark of the rest of the industry. The pilots are in line for huge raises they have failed to negotiate for the past eight years (because of their peculiar SLI dispute). Other employee groups will benefit from a merger as well.
