I am a loyal SW recreational traveler and have been averaging 5 flight per year over the last 5+ years. I always do what I can to maximize the points earned and have gotten to Companion Fare status for the last 3 years. In mid April this year I took vacationed in Vegas for a week and rented a car from Alamo using the SW code 7016141on the Amao site which should earn me 600 bonus points. I have done this in the past and the point have posted within a week. This time I am going on 2 month and still no points.
I am a bit frustreated becasuse SW says it is up to Alamo and contacty them and Alamo says they have sent the points and I need to contact SW.
My experience is that rent car companies are pretty bad at giving the bonus RR points that they promise. I have frequently had to contact them to remind them that they owe me points. It's happened with Payless, Dollar and Budget and maybe others.
Your post seems to indicate that you received the regular 600 points, but not the bonus points. If that's true, contact the company and tell it you want your bonus points. If you didn't even get the regular 600 points, as already suggested, contact the firm and make sure it has your correct RR number.
You could reach out to Southwest customer relations at 855-234-4654 and they might be able to open a ticket and the liaison who deals with Alamo would hopefully be able to help. My mom had this happen with payless and Alamo and after getting the liaison involved they were able to credit her the points.
Also just be sure Alamo has your name and correct RR number because if the name on the rental doesn't match your RR account that is probably the issue just like you can't earn points for your family's flights.
I also had a similar issues with getting the points from the partner super shuttle and after getting that liaison involved I was able to get the points so it won't hurt to try contacting customer relations.
