Quick answer
Here's how I'd set this up in ChatGPT or Claude (not run by us yet). Before booking, I'd paste in the cash price, the points price, the taxes and fees on the award, and my point balances, and have the chat work out what each point is worth on this trip. Then I'd decide myself and book on the airline or hotel site.

What does this setup do?
You give ChatGPT or Claude the cash price and the points price for the same flight or hotel, plus taxes, fees, and your balances, and it works out the cents per point, what you give up either way, and a plain recommendation. You book it yourself.
Who is it for?
For anyone with airline miles, hotel points, or card rewards who freezes at checkout wondering whether this is a good use of points.
How do you set it up?
Tools
- ChatGPT Free or Claude Free. Plain chat is enough, and web search can look up a program's published transfer partners.
- The cash price and the points price for the exact same booking, from the airline, hotel, or card portal
- Your point balances and any fees the award adds
Steps
- Find the exact same flight or room priced in cash and in points. Note taxes and fees on the award too.
- Paste those numbers into the prompt below with your balances and any points you'd earn by paying cash.
- Read the math: the cash price minus award fees, divided by the points, gives cents per point for this booking.
- Ask what you give up either way, like the cancellation rules on each option or points you'd earn by paying cash.
- Check any transfer partner or ratio the chat mentions on your card or loyalty program's own site. They change.
- Book it yourself on the airline, hotel, or card portal.
Example output
Illustrative. Your results will differ.
- Cents per point worked out for 1 round trip, with the math shown
- Points earned by paying cash factored in
- Plain recommendation plus the break-even number. Nothing booked.

Copy-paste prompt
Adapt bracketed fields to your situation.
Help me decide whether to pay with points or cash for one booking. Don't book anything.
Booking: [flight route and dates, or hotel and nights]
Cash price (total with taxes): [amount]
Points price: [number of points] plus award taxes and fees: [amount]
Program: [airline, hotel, or card program]
My balance: [points]
Points I'd earn if I pay cash: [number, or "not sure"]
Cancellation rules: cash [rules], points [rules]
1. Work out cents per point for this booking: (cash price minus award fees) divided by points, times 100. Show the math.
2. Note the points I'd earn by paying cash and how that changes the comparison.
3. Compare the cancellation and change rules.
4. Give me a plain recommendation and the one number that would change it.
Rules: Use only the numbers I gave you. If you mention a transfer partner or ratio, say it needs checking on the program's site. Don't invent point values.Newsletter

What usually goes wrong?
Where agents tend to stall on this job. More patterns in Where AI gets stuck.
- There's no official value for a point. The math only shows what a point is worth on this one booking.
- Award availability and prices change fast, so a number you got an hour ago may be gone at checkout.
- The chat can be wrong about transfer partners or ratios. Check them on your program's own site before you move points.

Common questions
- Should I use points or cash for my flight?
- Work out cents per point for the exact booking: cash price minus award fees, divided by the points, times 100. If that beats the value you've set for your points, points can make sense.
- How do I calculate the value of my points?
- Take the cash price, subtract any taxes and fees you'd still pay on the award, divide by the points needed, and multiply by 100 to get cents per point.
- Can ChatGPT tell me if a points redemption is a good deal?
- It can do the math and compare cancellation rules from the numbers you give it. It can't see live award prices, so you pull those from the program's site.
- Is it better to save points or use them?
- It depends on your plans and the value you'd get today. A simple rule is to set your own cents-per-point cutoff and redeem when a booking clears it.
Where should you go next on this site?
What tips make it smoother?
- Compare the exact same booking. A cheaper cash fare with different bags or cancellation rules isn't a fair comparison.
- Award taxes and fees can be large on some routes, so always subtract them before dividing.
- Save your own cutoff, the cents per point you're happy with, and ask the chat to compare against it each time.
