Sounds like Ecuador is the intentional route.
Not sure how you can say NK likes the midwest. (depending on how you label the midwest)
No STL, IND, BNA, MEM, CVG, CMH, LIT, OMA, OKC, ICT, DSM, and others.
All they have is MCI, MSP, ORD, DTW, CLE.
I'm from Florida so the Midwest as I know it begins as far east as Pittsburgh, south as Cincinnati, west and North as Minneapolis, I'd consider Kansas City the far west Midwest. In terms of frequency, DTW and ORD hold a pretty heavy amount with decent ops at CLE, PIT, and MSP, far more activity than most parts of the US other than the Southeast, which is where most of these flights are going.
I believe NK is going to expand their Midwest profile by adding IND and STL next, AUS is Southwest, RDU is southeast, BNA I guess could be considered Midwest since technically it's in the middle between the Southeast and Midwest. (in my case all of these are north lol).
I figured we had different definitions haha. For me midwest is Kansas/Denver border to Ohio/Penn Border (with Ohio kind of being a tweener). Tennesee is kind of a tweener for where it changes to south, but I was throwing it in for this. I don't like putting MSP, MKE, DTW, and ORD in the midwest but I think you almost have to since I don't count North as a region. It is always interesting to see different peoples takes on geography.
It is different everywhere you go, I just looked up a graphic of what states belong to which region; ME, VT, NH, RI, CT, MA, NY, NJ, DE, PA, MD make up the Northeast. WV, VA, NC, SC, GA, AL, MS, LA, AR, TN, KY and FL are the Southeast. OH, MI, IN, IL, WI, MN, ND, SD, IA, MO, and KS are all part of the Midwest. OK, TX, NM, AZ is the Southwest. CO, WY, MT, ID, UT, NV, CA, OR, WA, AK, and HI are the West.
Resort and other ground transportation options are on level 1.
