Chase Ultimate Rewards Redemption Rates

Hi! I have 2 Chase cards, CFU and a business Ink Preferred. I have some UR points on these that I was looking to redeem using the travel portal. It looks like the business UR will redeem at 1.25, and with nothing mentioned for CFU, I’m assuming it’s 1:1.

My brother who is also booking that same trip, and has CSP is able to redeem at 1.5. Is this right/ expected? I have never redeemed UR before. I’m not seeing any transfer bonuses better than 1.25 at this time. Can someone done help here? If this is standard, I’ll just bite the bullet and complete the booking! Thanks.
