OK, I must admit I'm not that familiar with Chase Sapphire, so I went and did a check on it for my travel pattern. Example my QR J award flight from DOH-HND runs $2910.13 if paid for with cash.

I booked this using AA FF miles for 40K miles + $13.05. So using an AA CC at 2 miles earned per spent on AA tickets, so $20,000 spend. FYI, I'm only using this for comparison as I don't have an AA CC as I earn enough miles from travel.

With Chase Sapphire reserve I would earn points at 3x points/$ spent on travel as best I can tell and according to info from Google on Chase Ultimate Rewards redemptions (points guy, etc since Chase's web site is not friendly from a rewards redemption perspective - it probably is if you're signed in) the best return appears to be redeeming 50K points for $750 value. So the $2910.13 ticket would cost 194K points as best I can tell. Or, a better redemption appears to be transferring Chase points to BA and get a BA award for 75000 Avios + $ 110.44. So in other words $25,000 spend.

So quite close IMO.

Now when using Chase Ultimate Rewards for Hotel awards, does one have to book advanced payment/non-refundable rates when using Chase points? Without the info readily available, it's really hard to tell.

As I mentioned earlier I was unable to find details on redeeming Chase points, so if you have a link to the details it would be greatly appreciated. I don't know if it would be something that works well with my travel paradigm or not, but it would be worth investigating. Thanks.
