Talk about "non-functional". My JB points from Barclay posted last night. I have 82,106 points. I go to redeem for a Mint seat. 105,000 points. I pay with points+cash. The slider goes up to 81,690 plus $408.10 I click Checkout. It changes from $408.10 to $5,622.21 and 81,653 points. WTH?

I've tried different browsers and even changing the slider bar. No matter what it shows on that screen in dollars, it changes to THOUSANDS when you click checkout. The flight, in pure cash, BTW is about $1,100 and total points is 105,000.

Update:
So after 45 minutes in "chat" with a JB rep who disconnected me as "resolved", I got another rep who didn't bother reading what I'd chatted, but eventually I was able to get it through to her what was going on (you apparently cannot send screenshots in chat). She saw the same thing and checked with her supervisor. The story is apparently there's certain fare buckets that need to be available for points+cash, and it wasn't available, so it was pricing the cash portion as the FULLY REFUNDABLE fare (which is like $7,000). I'm not sure I buy that since the full cash (non-refundable) fare was available, but I don't know enough about JB Fare buckets and all the inner workings. So the website is still glitchy in that it initially prices out as the cash portion/non-refundable price, but when you click Checkout, it changes the cash price (and the points as well).

Fortunately I have Chase UR and transferred 23,000 points over to get the full 105,000 points and booked. May not be the best use of Chase UR, but 105,000 for a $1200 ticket (1,180 or so) seemed not terrible.
