I've heard great things about the Chase Sapphire cards, but never got one of those or looked into that. I see them mentioned at the top of lots of places that review travel credit cards. Southwest usually makes the list too of one of the better cards, but those Chase Sapphire cards are almost always listed at the top.
I really don't do all that much travel -- next year for example two vacations where I'm flying and one little get-a-way long weekend where I'm flying and that's it and is pretty typical for me. And two out of three of those are Southwest (one is a rare international trip -- more like once in a lifetime vs. regular travel for me). I tend to stay in the good ole USA mostly. Southwest is by far the largest carrier out of our home airport and in so many markets are really the only good choice for me.
I have a Southwest card and love it. What I especially love about the points are that I can make reservations with points for family members who aren't sure they will be able to travel way in advance with good deals and get all my points back if they cancel out. We for example are doing a family reunion in Sedona, AZ next year (flying in and out of Phoenix) and I used my points to get tickets for my 85 year old dad who wants to come, but wants the option to back out if he's not up to it. I also used points for my son's boyfriend who really wants to come too, but isn't sure he'll be able to swing it with work / school schedule. So I booked flights with good deals for amount of points used and I can cancel even just a day before and get the points back and points can be used for anyone unlike travel funds. Love, Love, Love my Southwest card.
It's super easy to book with points and use points.
