I just signed up for PRG. With $2k spend in first few months, I rec'd an additional 25,000 miles. Used it to buy airline tickets. Also going to get the $100 credit because I am going to check my bags on it this month when we fly. So with no annual fee for the first year, I am getting free checked bags, and bonus 25K miles. For me, it is worth it. Now next year may be a different story, but for now, it is working for me.
Additional note however! I put $2.1K on the card for airline tickets and hubby bought a sports watch. I had a call from Amex asking about my payment. I told them I had an autopay for 5 days later to pay off the balance in full, before the statement cut. Rep says okay, thank you. I logged in after the phone call, and all 3 of my cards are frozen until I paid off half the PRG, $1K! WTH? I paid the thousand they asked for, and they reinstated all 3 cards within seconds. But I was furious. Why give someone a NPSL and then cut off all their cards? My other two cards were at 0 balance, BTW.
I made a few phone calls to Amex and one rep basically said for the first six months, don't put more than 1K on the PRG before paying it off.
Honestly, I am going to use it for checked bags to get my cash back, but I don't have any plans to use it again, except maybe for airfaire points. I am afraid to even touch the stupid card. I understand they get spooked, but my goodness. I haven't been paying every single bill diligently for years to get a lousy $2k and run from Amex. Oh well.... I was excited to have the card but quite frankly if I hadn't logged in to see I was frozen, I would have been declined had I used any of their cards. Unless there is a direct benefit for me, I won't use the PRG again. Just my humble two cents
