so if people signed up earlier this year for personal plus and then sign up for premier now (or vice versa), are they still getting the 50k bonus points again?

from the fine print:
"This one-time bonus offer is valid only for first-time Southwest Airlines Rapid RewardsŪ Credit Card cardmembers with new accounts. Previous and existing Southwest Airlines Rapid Rewards Credit Card cardmembers/accounts are not eligible for this bonus offer. Note: the bonus may be earned on one first-time personal and one first-time business Southwest Airlines Rapid Rewards Credit Card new account."
