This promotion is designed for the last minute bookings that don't mind paying high fares. Many of my September tickets are $29 instead of the $114 fare offered today or the $63 offered last week. So I'm paying an extra $170 for a 2-month CP. Or I could do a MR for $90 RT last week of Sep and pay $90 extra for the CP. Historically, I've only been able to use the Jan-Mar promotional CP once a year. No thank you.
