Booked about 2k worth of Delta flights through the Bilt portal using my Amex Platinum and it did exactly what I hoped, Bilt coded it as direct with the airline, so I got the full 5x MR. Plus the 1x Bilt for using a linked card.
So that’s 2k Bilt + 10k MR on a single booking. Not life-changing, but a pretty sweet little stack I don’t see people mention much.
Nice option if you’ve got Bilt linked cards or you’re hunting status there.
