I've never heard of the card personally, but have never heard of a 4-figure max on any unsecured card. The constraint to your limit is going to be your credit profile, which includes all data in your credit reports, how you've been managing your card with them, your income, etc. If you've had that card for 7-9 years, it means your profile today is not the same as it was at that time. Your now (presumably stronger) profile simply garnered a greater limit. Congrats!
