USA Airline Hubs

So apparently some people are getting a little confused over which airline to use when flying over America. I would know this, because there is that one random person that flies RyanAir from KJFK to KLAX.

Rest assured, I will complete this mini-guide to help y’all that seem to have a little trouble with it. I’m American, and I can’t figure out the airports that support Norwegian Airlines. (pls help)

I will go through every major airport in the United States and list the airlines that have placed a hub there, a focus city, or represents the majority of passenger traffic. East to West.

Hope this helps some of you!!
If you have a question about an American airport that I didn’t list, don’t hesitate to ask me.

EDIT: Changed some information regarding Southwest Airlines, Spirit and JetBlue.

Yes, Southwest can fly to Miami but not on a regularly scheduled flight, Miami is an expensive airport to fly in and out of, landings slots, gate costs, etc etc. So they choose to fly to the smaller and cheaper KFLL some 20-30 miles north. ;)

Because they have an entire terminal at KEWR and they operate a few flights out of KLGA

Umm… Spirit and Frontier sure as hell don’t have a hub in Chicago… Also KJFK is considered an American hub, Boston is considered a focus city by Delta. I believe, there are other inconsistencies but J suggest you check this a little.

KPIT is a hub for Sun Air Express! Let’s hear it for the Sun Air!

Sum what more importantly we are a focus city for Allegiant and OneJet…

Allegiant Airline base in Las Vegas

I didn’t say we were their primary place…

Southwest, Jetblue, and Spirit do not have Hubs. They use focus cities which may appear as hubs but are not in fact hubs. This is because they do not use the hub and spoke model and aircraft are not based at any airport just that most of their pilots are based out of there. This doesnt match the traditional hub and spoke system where an aircraft flies to a non hub airport and returns back to the hub, unless the destination airport is another hub for that airline in which case the flight is a aircraft movement flight mainly. Focus cities are just cities where there is a high presence like a hub, but the aircraft do not return to that hub afterwards.

That’s what I thought, but I was too lazy to double check… 😂

And I’m too lazy to write that out…

Don’t forget, UA has chartered flight to both KMDW and KHOU. They even have a maintenance base in KHOU (!!) and they regularly move aircraft between it and KIAH.

You don’t have to write it out, just list them as “focus city”…

To some extent Spirit doesn’t even have focus cities. They are a true example of point to point flying. They find routes that work and fly them. Southwest refers to their “focus cities” as operating bases. Similairly JetBlue lists KJFK as an operating base and their other airports with large operations as a focus city.

That is true, Southwest JetBlue and spirit aren’t considered “hubs”, but let’s take Southwest for example. Yes, they only offer one type of aircraft, but they still offer enough connecting flights to be considered a hub. Although it isn’t considered as a hub officially, it definitely provides enough to have a few main airports. Specifically KLAS KMDW KDAL KMCO and KBWI. These airports offer the most connecting southwest flights, and actually maintain pretty high passenger traffic throughout the airport. If it really bugs you, I will go back and fix it.

So you say that they offer enough flights for it to be considered a hub, and then state that it is not technically a hub. For simplicity sake why don’t we refer to them as focus cities.

I have gone back and edited it for all of those conserned about focus cities.

KISP is also a Focus City for Frontier.
And BDL isn’t a focus city for either JetBlue or Southwest.

It’s not a focus city as stated, those two airlines account for the majority of passenger traffic tho
