RE: You might consider opening another card....
Try to understand the factors that affect your credit score:

- New credit
While new credit accounts for 10 percent of your total FICO credit
score. But this doesn’t mean that opening multiple credit lines at the
same time will improve your score. In fact, such behavior could
suggest you are in financial trouble by needing significant access to
lots of credit.
“We encourage consumers to apply for and open new credit accounts only
as needed,” Lee said. “New accounts will lower your average account
age, which will have a larger effect on your FICO scores if you don’t
have a lot of other credit information.”

My Capital One credit card account reports monthly FICO scores and has a credit score simulator. In my situation, if I simulate canceling my oldest credit account, my FICO score wold be reduced by 2 points.
