A few questions ..
Does UR transfer to SW 1 to 1?
If you book SW using UR, how does the companion pass work?
Thanks in advance.
I found the answer to my questions and I thought it might be of value to post it.
UR transfers to Southwest 1 for 1. If you have the reserve card, 10,000 points are worth $150. The value of Southwest points are 1.43 cents so 10,000 RR is worth $143. Booking using UR seems a better route. If you have the preferred card, 10,000 UR is worth $125.
If Southwest is a viable option, the real benefit seems to be UR in combination with the companion Pass.
I found this information on the internet.
"With the Southwest Companion Pass, Your Chase Ultimate Rewards Points Are Worth Even MORE. Because a Companion Can Fly With You for (Almost!) Free, Even When You Book Your Ticket Through Chase’s Travel Portal."
It was pointed out to me that you can't book Southwest on the Chase Portal so I got on it and I found..
"Some airlines don't offer advance seat selection. Southwest and Allegiant tickets can only be purchased by calling us at 1-855-234-2542."
So bottom line you can combine the two programs.
