I have two Penfed cards - Cash Rewards and Promise. Cash Rewards was opened in August 2014 for $1,000 SL. In March 2015, I requested a CLI and it was bumped to $10,000. At that time I also applied for Promise and was instantly approved for $14,500. Today I decided to hit the CLI button:
Cash Rewards instant to $13,500 (from $10,000)
Promise was pending then approved after two hours to $20,000 (from $14,500)
I applied for PLOC but that was denied. I'll wait 88 days and try again.
