Length of credit history needed for amex revolver

[HiLine]

6 months.

I have not heard of anyone getting approved with less than 6 months, and I know people that got approved with 6 months (without a previously obtained Amex charge card). I myself got my first Amex credit card with 10 months of history without a prior Amex charge card.

I got approved for a Amex BCP card this month with 7 month of history. 1st card being PNC secured card. I was triple pulled and approved for a 2000 limit. I have ex:8, EQ:6, TU: 6 inquiries as most lenders have triple pulled my cr. I maintained util between 1% to 5% on all my cards with max 2 cards reporting each month. I got the 250 bonus on 1000 spending offer in the mail. I was added as an AU to Amex Delta card in the month of May.
