It’s ranked by PDEW (Passengers Daily Each Way).

There’s quite a few unserved routes from airports like San Diego (SAN), Hartford (BDL), Jacksonville (JAX), Sacramento (SMF), San Antonio (SAT), and Raleigh/Durham (RDU)

Wow! I never heard of these routes before haha…


This is a very interesting chart, I saw something about it on @tampa_airport_spotting’s Instagram (I suggest everyone follow him). BTW I believe all of the Hartford, CA should be Hartford, CT. Talking about BDL, I fly there a lot and would love to see them get some new routes.

Fun Fact: I believe BDL is the smallest airport with a TATL flight in the US (they get service to Dublin on Aer Lingus on an A321xlr)


Lol I even fixed it before but I guess it didn’t save that one.

I think Charleston is the smallest airport with TATL service on British Airways’ 787-8 to LHR.
CHS - 4.5 million passengers
BDL - 6.4 million passengers


Ah my fact was outdated, a few years ago it was true because they had Norwegian service to Dublin on a 738


Ugh, I really would love it if PHL-SJC was added

But AA decides to add SJC-AUS, a route already served by 2 airlines 🤦‍♂️


Well… then there was Stewart SWF Airport with only 300,000 passengers that had Norwegian to Dublin, Shannon, and Cork.


Jacksonville and Raleigh seem to appear time and time again.

Never heard most of that route but pretty interesting!

Glad to see Philly on here 3 times, I could see Southwest opening PHL-SMF and PHL-SJC and I think AA could be able to fly a 738 into SNA

I really don’t see that route being a possibility with Southwest, especially when Southwest is overshadowed by American at PHL. I do see AA opening the route though

They already fly a B738 into SNA. They fly the plane from SNA to DFW, PHX, and ORD

Yay JAX is on here a bunch and I would love to see any of these routes done.

Ah, I remember when Southwest flew ISP-MDW a few years ago, then they cut the route. Really wish it would come back, I live near ISP and my family has been going to Chicago a lot and it’s a pain to get to LGA to fly into MDW. Frontier tried ISP-ORD about a year ago, but also cut that. Just wish Southwest would bring the route back!

Well Southwest has a pretty big standing at PHL, obviously not as big as American, but it’s the 2nd biggest airline at PHL

Problem with PHL-SNA though, they’d likely need to block seats on the 738 because of the range and SNA’s 5,700ft runway. Also, SNA is slot restricted.

But a route like PHL-SJC with them? I don’t see that at all

GJT-SFO is currently unserved but in high demand (they [GJT Officials] are trying to get this in service for summer 2020).
GJT-ORD was launched last summer ONCE a week on United with the E175 seasonally in the summer. According to the GJ Sentinel ORD is one of the top destinations for western Colorado travelers so an increase in service here could be essential.
And finally GJT-IAD. This might seem like a stupidly unreasonable route, BUT, the national BLM headquarters was moved to Grand Junction recently so this flight could be (and hopefully will be) reality in the next year or so. Don’t believe me? Read here;

Here are a bunch of routes to do…

Who even flies BWI-HNL?
