Be sure to provide your email address and opt-in for all 3 email subscriptions to get the full 8 credits.
6 credits will post immediately upon enrollment. The last 2 credits (for the email subscriptions) will post within 7-10 business days.

16 credits are required to get a free systemwide RT ricket on Southwest.
