Got CP on flights. Did not need help from the credit card. It’s been 100% worth it for me. I’d say that my wife flew 10 flights with me this year. Some were long hauls like MHT-LAS, while others were mid-range (MCO, DAL, BNA). As for street value, I’d say $2000-$2500.
What makes it easier now is that the kids are in college and we have a bit more freedom of movement.
PLUS... you’re not burining points on the flights. So, you’ve got $$$ in the bank.
