You can redeem UR points for Uber gift cards at a 1:1 ratio (1 point = 1¢), starting at 2,500 UR for $25. This is a really bad deal because you can use a CSP or CSR and earn, respectively, 2x UR or 3x UR when booking with AirBnB directly (travel category bonus), then "cash out" your UR points at 1¢ per point as a statement credit or deposit to cover the cost of your AirBnB booking. This is still a bad value, since you can redeem UR points at 1.5¢ per point via the UR travel portal.
For AirBnB, you have two options that I can think of offhand to save some more money or earn additional points:
1. PayPal Digital Gifts (PPDG) often runs sales on eBay for AirBnB e-gift cards.
You get the point that these 8-10% sales happen quite frequently, and tend to ramp up at the end of the quarter when PPDG and eBay are trying to juice up their sales numbers. Check Doctor of Credit regularly, because he's really good about posting gift card deals, or we can tag you here if you're interested.
or
2. MileagePlus X (MPX) sells AirBnB e-gift cards.
- You can earn 2 United MileagePlus (UA) miles/$1 on AirBnB gift cards.
- AirBnB gift cards max out at $500 on MPX, but you can buy several. (I would not recommend buying several $500 gift cards all in one day because you’ll likely trigger a fraud alert and could get your account frozen!)
- If you have a United MileagePlus Visa credit card attached to your MPX account, you get a cardmember bonus of 25% more miles on your gift card purchases.
- You don't have to actually use a MileagePlus Visa credit card to pay for your gift card purchase on MPX to earn the cardmember bonus; use another card which will offer you the rewards/points/miles that you value or a new card you're trying to meet a minimum required spend on for the signup bonus.
So for example, if I buy a $500 AirBnB gift card on MPX, I'll earn 1000 UA miles + 250 UA miles (because I have a MileagePlus Visa attached to my account) + 500 Starpoints (because I'm paying with my Amex SPG Business credit card).
then
3. Once you've bought your AirBnB gift cards, go to the Delta/AirBnB portal at
https://www.deltaairbnb.com, click through and make the booking on AirBnB to earn 1x Delta SkyMiles/$1 on stays. I see this program is also offering 1,000 bonus SkyMiles for new guests and a $25 coupon for first bookings.
