so first off i mentioned OP need to do more research on it

for exmaple, aa's trip credits can be booked for anyone, and it is possible to convert flight credit to trip credit. the problem is you may not be able to book aa tickets at 1.75 or 2cpp. since OP has CSP, he at least can at 1.25cpp. you are more likely to find such tickets for UA, but you cant use UA's credit for anyone afaik. im not too sure if that can be converted to travel certs which can then be used for anyone, but i did a quick google and it seemed someone managed to do so previously
