I am beginning to realize I am missing the boat on this "churnng" thing, but al so nervous and uncertain about it...i really need an expert opinion.
my deal: I am a diamond hilton and silver us air the old fashioned way--traveling for work--hubby and I just moved to charlotte and both jumped on the us air barclay deal--we LOVE it as we get priority boarding, etc and pretty much our goal is to fly only us air (or the new american

) because the prices are so great here....
I have had a hilton visa and amex for several years that i could easily cancel:
my goal honestly:
perhaps status at another chain (marriot is a big one for my company), i can easily earn diamond status at hilton on my own.
Should I drop the hilton visa and amex which are rarely used and get another card??? Is there a general card that makes it more advanatageous in general to charge everything but my flights? (I love using the us air card to book us air flights because of priority boarding, etc)
I really so appreciate your suggestions. Im not terribly comfortable with crdit cards and having a zillion but am definitley missing some opportunities I think.....
thanks!!
