You might need a small or odd number of points to snag an award ticket or hotel stay, but be aware that you must always transfer in increments of 1,000 Chase Ultimate Rewards points to travel partners.
You can combine any number of points between Chase Ultimate Rewards cards (yup, even just 1 point) or combine them with others in any amount.  But when it’s time to send them to travel partners, they have to go out in increments of 1,000 points.
