Update: No longer working.
Last week reader audi0l0gic posted a comment letting us know that their payment through Plastiq using the Chase Sapphire Reserve Capital One coded as lodging/travel. For some reason, I disregarded it as I thought it had always coded that way but didn’t earn 3x points on the Chase Sapphire Reserve. Harlan from Out and Out just earned 3x points from a Plastiq purchase on the Chase Sapphire Reserve as well.
It seems only rent/mortgage payments are coding this way. Keep in mind if that you’re new to Plastiq you can earn $800 in fee free payments, if you’re an existing user you can share your referral links in that post. The fee to pay bills/rent/mortgage with Plastiq is 2.5%, if you’re earning 3x Chase Ultimate Rewards for the purchase you’re ultimately coming ahead as if you redeem those points for cash they are worth 1¢ each.
