What unused gates? Every gate from the security checkpoint down to C56 is in active use. One by Alaska, the rest by DL.

Columbus is awful.

Go Blue!

I kid.

Kinda...

Not every Delta location has a Skyclub. CMH happens to be one that doesn't. Apparently DL has not determined that it is in their best interest to put one there, at least for now. Maybe some of the earlier posters know something about the market that Delta doesn't. Or maybe they just have superior business judgement..

Fear not. Columbus is in America. Anyone is allowed to acquire sufficient capital and open an airline club in an underserved market, thereby earning a ton of money. That's how the system works.

Miami and Nashville don't have a population of 800,000. But, Houston, San Antonio, and San Jose do have more than 800,000 and they don't have Sky Clubs.

oh so did I

"The airline industry continues to face very difficult economic conditions and the outlook for the foreseeable future offers little relief," Douglas Parker, America West's chairman and chief executive, said in a release. "A necessary and critical component of restoring industry profitability is the elimination of consistently unprofitable flying."

During a roundtable over the summer, CMH's CEO said that a SkyClub would likely be part of a Europe flight (provided it was Delta service).

DL's decision where to place SCs is all about premium and elite passenger volumes and not total passenger counts. From DL's POV there must not be enough volume for the numbers to work. Not only do the number not work for DL, but they seem to not work for AA or UA either, and AA has more traffic in and out of CMH than DL does.

No SC aside, the DL terminal in CMH, and the CMH airport as a whole is so bland and uninspired. Limited food options post-security worsened by the fact that the three concourses are not connected post-security. A major fail for an airport this size. Not an airport on the top half of my favorite airports list.

You are the one splitting hairs by using an arbitrary metric to justify the existence of this thread. City population is 100% irrelevant. It's based on city zoning which is largely arbitrary. If you use metro area you would at least be halfway logical.

CMH doesn't serve a huge amount of passengers. Full stop. That's a massively more important metric for an airline and whether they make capital investments at an airport.

Delta has ~32 domestic SkyClubs and CMH is the 50th busiest airport in the USA.

CMH is a mid-size airport and DL isn't even the airline serving it with the most flights. There are other factors besides airport size, like premium traffic and international routes. CMH must not rank high enough in these to make it. Hardly a surprise.

But these airports have other options, be they lounges run by partner airlines (until this year, you could access the KLM/Air France lounge in Houston) or third-party lounges accessible with Priority Pass.

Fair enough.
