[Update January 2014] Looks like this has become a regular practice - Chase will keep the links alive for a limited time and then deactivate them for a while before bring them back to live again. The landing pages never changed and if you can't access them that means they got pulled - no worries just stay put until the next round. This time the application links are a little different from the previous ones, and even though I believe the old ones still work I just go ahead and replace them with the new ones anyway. Another thing to note is that after March 31, 2014, the value of Southwest RR points will be devaluated from 1.67 to 1.43 cents a piece, as covered in this blog article. Please scroll down to the bottom of the post to apply!
[Update November 2013] While those links were pulled for a while, Chase made them available again in late October. They are using the same links! So here you go until they get pulled again.
[Original Post June 2013] While the standard offers for Chase Southwest Visa have been always 25,000 points for each card, Chase has run many times the special limited time offers of 50,000 points (=$833 Wanna Get Away fare) for each card. We have noticed that the previous links for Plus Visa have expires. Even though the previous links for Premier Visa are still alive, we want to just go ahead and update links for all four cards in this post.
For each card, you need to spend $2,000 within 3 months to get 50,000 points. The annual fees (noted below) are not waived. It is pretty safe to open one personal and one business card to get 100,000 points. If you open two personal cards (or two business cards), you may get 100,000 points but there is a risk. If you want to push hard, you may try all four at once, and there is a potential to get 200,000 points!
