Interesting.
I had/have a Capital One card for the business with a 50K limit on it but the Cabelas card is so much better that I parked the C1 card in the drawer. I have a much less than 50 limit on the Cabelas card and I regularly take it over limits but I pay the balance in full every month and if I do take it over, I call in advance (Cabelas) and tell them....
Just happened a week ago. The wife wanted a pair of diamond earrings with emerald centers. Gave Cabelas a jingle on the cell phone while I was at the counter in the jewelry store, shot them the price and charged it. The wife has a thing for emeralds.
Last time I checked my Trans-Union credit score, it was well above 800 so having a card unused with a big open balance don't seem to have any ill effect on my score.....
Don't need air miles, don't like to fly anyway, at least not commercial. Private jet is so much easier. No baggage check, no x-ray machine, no waiting and good liquor in real glasses and if you happen to forget to leave your pistol at home, no biggie.
Bad JuJu on a commercial carrier.....
