How frequently should I request additional credit?
I don't know of a guideline to how often you can ask for an increase. You can ask as often as you like. As for consequences, refer to Is there a downside to asking for a credit increase?, where the consensus is that, aside from a possible (temporary) hard pull on your credit report, there's probably no risk to asking. Depending on your credit score/history, and especially in the current economy, you may get "no" as an answer most often. You can try talking to your card's Credit Department or even Customer Retention Department as they may have more leverage. They may say yes or no or that they need to review your account. When you do ask for an increase, I would make sure to ask if there will be a hard pull on your report, if there is any cost or downside to applying, and to make sure that this would be an increase to your current credit line, not a new account.
