I guess I should take one for the team and try to cancel a WGA Chase portal booking. I would expect to get Southwest travel funds, but I could get nada. If it's travel funds, that would have me seriously considering getting a Sapphire Reserve card.
Never mind. Others have tried it months ago and confirmed that you can't get Southwest travel funds if you book through Chase. So no 1.5 cents of travel funds per Chase point. The best option is still 1 RR point per Chase point and use the RR points for sub-$100 flights.
I am assuming it will work just like when I use AMEX points to book WN flights. I do this because with the Business Platinum, I get 35% of the points back. When I cancel, I do NOT get WN travel credits I can use directly. I get AMEX travel credit for WN flights.
similarly, if I want to rebook because the fare went down, I cannot make the change myself online. I have to call AMEX Travel to cancel then rebook with the credit leaving me with the remaining still as AMEX credit.
