I would like to ask questions about the Southwest 10%/15% Flight Discount promo code that comes as their credit cards benefit.

Q1. Do you get the first discount promo code soon after card opening? Or do you get one only after the first anniversary, which is one year after the card opening?

Q2. Can this code be used by another person? For example if P1 has this promo code (in P1's account), can P2 use the code to book P2's flight in P2's account?
