Since you are doing a little bit of traveling I now will suggest some executive cards but first the Southwest card. 1 of my cousins has the card, he loves it not sure if you get concierge service on this card. There's an annual fee not sure how much, it's waived the first year.
My Capitol One Venture card is 1.25 miles per dollar, concierge service for hard to find gifts, travel, dining, sporting events they can help.
The Starwood Preferred Guest from American Express is great card. You rarely see anybody use this card because it's mostly thought of a business card, used for business dining, airfare, and hotels.
the 2 cards are great.
Chase has the Marriott, a very good card for business travel, not sure what the points are.
To be honest all of them are a higher level than my American Express Green card. Which in its own right is also an executive card.
I think you qualify for the Southwest card offer
, since you have a Citibank Forward you might.
It's not like you have Walmart, Macys, Target, or Sears charge card. you actually have a credit card.
The 50,000 miles should be open to new members if they qualify I think you should. If you said everything about yourself the same, but no Citi and instead store charge cards, then I might have said you would have trouble getting this card. But since you have Citibank I think you will get approved.
