The Bilt Mastercard® (review) is a valuable no annual fee card that I applied for and hold onto. This allows you to pay your rent by credit card and earn rewards, even if your landlord doesn’t ordinarily allow no-fee credit card payments. For us homeowners, you can potentially even pay your HOA this way.
There are many innovative things about Bilt, including that there’s a Bilt Rent Day promotion on the first day of each month. With it now being a new month, I’d like to post a reminder of the December 2025 Bilt Rent Day offer, as it includes a big airline transfer bonus.
In this post:
Details of the December 2025 Bilt Rent Day promotion
There are a couple of aspects to the Bilt Rent Day promotion, including the ability to earn bonus points (which is the same every month), plus at least one additional promotion.
Note that Bilt Rent Day promotions are generally valid from 12:00AM ET until 11:59PM PT, so technically you have around 27 hours to take advantage of them.
Earn 2-6x Bilt points on Rent Day purchases
Ordinarily the Bilt Mastercard earns 1-3x points per dollar spent, as you earn 3x points on dining, 2x points on travel, and 1x points on all other purchases. On the first day of each month, you earn double those rewards, meaning you earn 6x points on dining, 4x points on travel, and 2x points on all other purchases (except rent, where you earn 1x points).
With this offer, you can earn up to 1,000 bonus points each month. Keep in mind that you need to use your Bilt Mastercard five times each statement period in order to earn these points. It could be worth strategically making some purchases on the first day of each month to maximize this as much as possible.

Get up to a 100% IAG program transfer bonus
For the December 2025 Rent Day promotion, Bilt is offering a transfer bonus of up to 100% when moving points to any participating IAG airline, which includes British Airways Club, Iberia Club, and Aer Lingus AerClub.
The size of the transfer bonus depends on your Bilt elite status, as follows (this is available exclusively on December 1, 2025, between 12:00AM ET and 11:59PM PT):
- Blue members receive a 50% transfer bonus
- Silver members receive a 60% transfer bonus
- Gold members receive a 75% transfer bonus
- Platinum members receive a 100% transfer bonus
There are plenty of great uses of Avios, especially since you can freely move the points around between programs. I don’t think everyone should necessarily take advantage of this, but if you have one of the higher status tiers, then this could represent a very good deal, if you ask me. After all, Avios are just a very useful currency.

Bottom line
On the first day of each month, those with the Bilt Mastercard can take advantage of the monthly Rent Day promotion. In addition to earning up to double points for purchases, for December 2025, there’s the opportunity to take advantage of an up to 100% transfer bonus to British Airways, Iberia, and Aer Lingus. This offer is absolutely worth considering, so if you’re interested, now is the time to make a transfer.
Are you taking advantage of the Bilt Rent Day promotion for December 2025?
Ahhh, if I only had rent or mortgages. I’d rather be debt free.
Apparently, you’re not following the ‘buy, borrow, die’ tax avoidance strategy, because the super-rich supposedly enjoy ‘debt’ more than you’ll ever know…
