For me used to like getting large CL. But my oldest card started at a 6k limit 10 years ago. I never asked for a CL increase.
It is now 22k. I believe that if a CL is big enough to support your spending needs and not go over 80% then I think it's fine.
A person once told me that when you use a credit card it sin't your money.
I wish I had thought this way from the beginning.
A CL only needs to be large enough to buy what you need and allow a few weeks to pay it back.
if you ask for credit oncrease too much you have to worry about HP, fanincial reveiws, or moving CL from act to acct.
I am a firm believer in just letting the lender increase your CL as they seem fit.
