<prompt> Human: Tried to search but came up empty.I have one credit card with a 35k limit and another with an 18k limit. I obtained both by telling the credit card company that I wanted to make a large purchase and desired to use their card to do so all of which was true. I then paid the balances off in full. But since then I have never even come close to my limit.Will the credit card company ever decrease my limit if they see that Im never coming close to reaching it? Is there anything I should be doing to prevent this from happening?If I wanted to try and increase my limit even more, would I have any shot? I dont really see any reason to do this because my utilization ratio is always very small anyways for typically not carrying balances, but just curious.  <response>: Most likely not. They may however decrease your limit if your credit situation changes which includes but isnt limited to delinquency, bankruptcy etc.
