So Southwest is adding service to Dallas Love Field. I make a monthly trip to Dallas, so I was excited! Then I found it was on Sunday only. What is the purpose of this route? Perhaps when Spirit's seasonal service is over in November, it will get some passengers, but the fares will be too low for a once weekly flight while Spirit is in the mix. It's a shame; DAL is a nice airport and pretty convenient. Hopefully, they are just "testing the market" and may have daily service later on.
