As long as you were comfortable using a 5/24 slot on the Freedom then it's a good decision for you
Regarding the MiddleName LastName thing - this really depends on your comfort level. Tons of people advise ordering a card using a nickname, or with a dog's name. I like to go middle last because that could be a nickname I'm called and I did once ask Chase a long time ago if I went by my middle name and wanted to change my card to that rather than my legal name how to do that and they said just order an authorized user card. Soooo right or wrong I stick with that one
For card opening dates I use the free Experian tracking service (not the pay one) and it updates once a month which works for me just to verify accounts and inquiries.
Southwest has this neat interactive route map: https://www.southwest.com/flight/routemap_dyn.html
From Detroit they fly nonstop to: Las Vegas, Phoenix, Denver, Dallas, St. Louis, Chicago, Nashville, Atlanta, Tampa, Orlando, Baltimore.
I know nothing about other airlines lol sooooo not your guy on that question otherwise.
EDIT: You could try to call and recon your Freedom card. First it'd be nice to know if you're approved or what your status is though...Did you try calling the automated status line to see what message they give you? It's been awhile but I think you call 1-800-432-3117 and follow the prompts (I think you'll hit #, 3, 1 to get to app status). Tell us what that message says and that can give you an indication on whether you're approve or not.
