Say on the conservative side they started serving XNA with 5 or 6 flights a day somewhere...that's 1000 new seats on 737s that are seats dumped into the XNA market, a market with a total of ZERO Mainline flights ANYWHERE on US3 aircraft, that oh by the way only have half the capacity into XNA of any aircraft WN would use. If there was more demand the US3 would fly bigger planes or greater frequency.
WN is NOT HAPPENING in XNA. everyone who wants to fly Southwest will keep driving.
I agree that WN will not serve XNA in the near future.
WN does serve markets smaller than XNA in Texas, including AMA, LBB, MAF, and CRP. However, DL does not serve AMA, LBB, MAF, and CRP, and WN has been at LBB, MAF, CRP, and AMA for over 39 years.
XNA does have nonstop service to AA's CLT, ORD, LAX, LGA, and DCA hubs, DL's ATL, MSP, and LGA hubs, DL's CVG focus city, and UA's ORD, EWR, and SFO hubs. On the other hand, AMA, LBB, MAF, and CRP do not have any nonstop service to these 10 US3 hub airports.
There is less need for WN at XNA than there is in the smaller Texas markets served by WN with DL serving XNA and with XNA having nonstop service to 13 US3 hub airports.
WN does serve LIT, but LIT is in a bigger metropolitan area than XNA is in. LIT also does not have any nonstop service to CVG, MSP, LGA, EWR, or SFO. On the other hand, WN does serve DAL, LAS, PHX, and STL nonstop from LIT, whereas STL and PHX have no nonstop service out of XNA on any airline. There are also more passengers who travel to and from LIT than there are who travel to and from XNA, with 1,930,000 passengers per year who travel to or from LIT vs. 1,371,000 passengers per year who travel to and from XNA.
