The aforementioned setup nearly always means the closer airport ends up getting upgraded later to meet convenience demands, leaving the newer-but-inconvenient airport out to dry.

See: Haneda (HND) vs. Narita (NRT) in Tokyo, Itami (ITM) vs. Kansai (KIX) in Osaka, etc.

When DFW was built Congress passed the Wright Amendment which kneecapped Dallas Love Field (DAL) to only serve domestic and immediately adjacent state travel. Personally I prefer DAL but I can see how DFW would have potentially withered on the vine if it hadn't been passed. I'm happy its finally expired though and now DAL can offer international flights.

Although now that there's a Whataburger at DFW one big argument for me for DAL is a bit less strong. When the Silver Line finally gets built, I imagine almost all my air travel will go to DFW.

Jesus. I just read the Wright Amendment article and it’s absolutely disgusting the level of regulatory capture and corporate cronyism enmeshed in our government in this country. There is no reason the federal government should be involving itself in these petty airline disputes, and certainly shouldn’t be helping maintain monopolies for reasons as bad as “American Airlines is the largest employer in North Texas”.

I largely agree with these opinions and dislike the cronyism that is a part of this deal. Looking at it a bit more holistically and seeing the growth of the DFW metroplex from 1980-now though, I think it makes sense for DFW airport to have succeeded. Having the very centralized airport with (theoretically) good rail service to both major cities makes a heck of a lot of sense and have been a good thing for the DFW economy. It would be nearly impossible to build the airport as it is now post that growth, but there's a good chance it wouldn't have survived in the early days given how far out there it was in 1979.

So short answer, I hate the cronyism, but many of the positive end goals marketed here ultimately did come true here. And it didn't fully kill DAL or Southwest in the end.

Not if the old airport gets closed - like Tegel and Tempelhof were in Berlin, even though the new one next to Schonefeld wasn't ready yet due to it being a fiasco of colossal proportions.

[Dalewyn]

Sure, like in the case of Hiroshima Airport (HIJ) and its predecessor (HIW), but even then most people (not necessarily including the politicians) end up longing for the one that was more convenient.

The issue for Seatac is that it's on a relatively small piece of land and can't really expand. They would definitely just go that route if they could.

Didn't happen with Denver or Hong Kong.

Or Paris.

In Washington DC, Washington National Airport (WAS) is just across a river from downtown and connected by subway, and Dulles International Airport (IAD) was way out past the exurbs when it was constructed and only just got a subway connection several decades later. IAD gets way more traffic and has as long as I can remember. I'd guess that's because it's not possible to add many more flights to WAS.

[massysett]

This is wrong. Reagan National is DCA, not WAS. Also, DCA handles more passengers than IAD.

Sorry, I take the train 10x more than I fly, I mixed up the airport with Union Station.

DCA and IAD have their work-load shared due to regulatory action:

> The Perimeter Rule is a federal regulation established in 1966 when jet aircraft began operating at Reagan National. The initial Perimeter Rule limited non-stop service to/from Reagan National to 650 statute miles, with some exceptions for previously existing service. By the mid-1980s, Congress had expanded Reagan National non-stop service to 1,250 statute miles (49 U.S. Code § 49109). Ultimately, Reagan National serves primarily as a "short-haul" airport while Washington Dulles International Airport serves as the region's "long-haul" growth airport.

> Congress must propose and approve federal legislation to allow the U.S. Department of Transportation to issue "beyond-perimeter" exemptions which allows an airline to operate non-stop service to cities outside the perimeter. As a result of recent federal exemptions, non-stop service is now offered between Reagan National and the following cities: Austin, Denver, Las Vegas, Los Angeles, Phoenix, Salt Lake City, San Francisco, San Juan, Seattle and Portland, Ore.
