New York City, Los Angelas, Chicago and Atlanta immediately come to mind, there's a whole list of the major passenger traffic airports I found on Source: Wikipedia.  

I want to be closer to a big airport ( my spouse job requires it) and want to flip and have some rental properties, in a landlord friendly, good rental market.

Medical Center (jobs and growth) and Hobby airport (cheap available transportation).

And then the new factories popped up and the ease of getting to the Indy international airport made it a nice play for us.   

So you might occasionally find me at the local airport wrenching on something or working on my student pilot license.So hello to all!

I was in the airport when I filled this in and was just giving a baseline public overview of my recent deal. 

We are 45 south of Houston Hobby, Southwest’s HUB and an International Airport.

Amex platinum has by far the best airport lounges far better than any domestic airlines lounge so for me that is worth the 400 a year for that card plus getting frequent flyer miles on virtually any airline a few years ago we used it to go first class from Hong kong to Phuket and did not burn a lot of miles. 

@Jess Haas around the seatac airport.

What is most important are access (near airport), safety, and location.
