Amex allows a credit limit increase on credit cards 60 days after account opening, and one credit limit increase, per card, every 6 months.
A credit limit increase can be done online or over the phone.
Recently Amex has been very stingy with me in credit on my new cards, the lowest was last August’s Platinum Delta SkyMiles® Business Credit Card for which I was only granted a credit line of $3,000. In 2013 I am going for the 10k MQM ‘Mileage Boost’ for reaching $25k annual spend, and then another 10k for reaching $50k, so I needed more credit.
I canvassed various sources and experts and the answer consistently came back that if Amex is going to approve a credit limit increase, the maximum is almost always 3 times the current credit limit. Further, that asking for more does no harm because they will just approve for the 3x credit limit.
I requested the credit limit online, asking for $10k, sure enough, it came back as approved for $9k, with the option to accept or decline.
This is a credit report soft pull, not a hard pull, so not worries about that.
Readers, does the 3x rule hold true for you?
