Well, we don't fly out of any of those airports but we did just switch from using our SW visa to the Chase Sapphire Preferred visa. Instead of earning SW-RR points, it earns Ultimate Rewards points. They are very flexible and if we want to convert them into SW points we can with a 1:1 full point value. We can also trade them in for American Airline miles, British Airways, and some others. We can also trade them into several hotel chain's points such as Hyatt, Marriott, and Starwood points. Or just book our travel directly through their UR points website and use 20% fewer points.
We've only had it approx. 1 week and so far I'm liking it. All travel-related charges earn double points as well as any restaurant. This also is a much better offer than the SW visa which only doubles points for purchases made to SWA.
I prepaid the airport parking bill for an upcoming trip (gets us the lowest coupon rate and allows us to redeem frequent parker points.) This also qualified for double points since it's travel related.
So even if we still wish to fly SW (still a few non-stops out of Philly!) we can always transfer our UR points into SW-RR points and it would happen much more quickly, or we can opt to save a huge amount of points and do something big with them. (Europe, Hawaii, etc.) AA flies just about everywhere.
There are so many places that SW doesn't fly to and they all cost more than flying to FL.
We just happened to be in a Chase bank for something else and were offered 50k bonus points to me and dh. Also if we add an authorized user (we both added each other) that gives us another 5000 pts. I'm hanging onto my SW card for now until I see how things work out. I've had it for 11 yrs and it's hard to let it go. lol
