Do you have the Capital One Venture card already?
If you and your partner can both sign up for the card, you'll each get 50K Venture points, which are redeemable for statement credits against most travel purchases. That would give you some flexibility. i.e, not just flights or just hotels, but both + car rentals, airbnb, Lyft/Uber, train tickets, etc.
You earn two points per dollar, and the fee is waived for the first year. So if you could get two of these and charge $7K to each, you'd have,
(7,000 * 2 + 50,000) * 2 / 100 = $1,280 to spend on travel.
If you had to sit on the points for a year, due to lack of travel, the fee is $95. So after one year, your net would be $1,280 - $95 * 2 = $1,090.
I imagine getting actual airline miles would be a more valuable redemption, but if you're looking for more flexibility, this is an option.
