Although, the international flight lock is still in place. Would it ever be realistic for WN to grab one gate at DFW for international flights?
To what end, if they start offering international flights in the metroplex one would also expect connecting traffic, how are they going to get them to DFW, by bus?
If they open up a sizeable DFW footprint they just have to go along with the increased cost and allow other LCC's to use the other cheaper airports in the region.
The region is already looking at more than just WN and AA so.....
There are currently only 11 destinations that have daily nonstop service to DAL on WN that do not already have daily nonstop service to HOU on WN, and these 11 destinations are AMA, BUR, CMH, DTW, LIT, LBB, ONT, PHL, SMF, SLC, and SFO. However, WN will be starting year-round daily nonstop service to CMH from HOU on October 3rd, and WN also already has nonstop service to HOU from OAK and SJC in the San Francisco Bay Area. WN also has Saturday-only seasonal nonstop service to HOU from SLC. BUR and ONT are both located in the Greater Los Angeles area along with LAX, LGB, and SNA, and WN already serves LAX and SNA nonstop from HOU.
WN has served HOU nonstop from AMA, LIT, LBB, and PHL in the past, and WN could bring back nonstop service to HOU from these 4 destinations in order to connect passengers to international destinations. WN also already has daily nonstop service from PHL to other international gateways, including ATL, MDW, DEN, and FLL. WN could also add SMF-HOU nonstop service in order to connect passengers from SMF to international destinations and domestic destinations in the Southeastern U.S.
There is enough room at HOU to accommodate at least 200 domestic departures a day on WN, and WN currently only does around 150 domestic departures a day at HOU. There is no need for WN to connect passengers from domestic flights at DAL onto international flights out of DFW since WN already has nonstop service to HOU from most of the destinations that have nonstop service to DAL on WN, since WN already has an international gateway at HOU, since WN still has enough room to expand domestically at HOU, and since WN can add more domestic flights out of HOU if needed for international connections.
In addition to HOU, WN can also connect passengers onto WN international flights out of ATL, AUS, FLL, and MCO from DAL. FLL is also a major international gateway for WN, and WN can also add more nonstop international flights out of ATL, AUS, and MCO. DFW also already has nonstop service to Mexico on AM, 4O, NK, SY, and Y4 in addition to AA, and DFW also already has nonstop service to some Caribbean destinations on NK, SY, and Vacation Express in addition to AA.
