How to Use Muse to Find Cheap Flights
Use Muse to hunt flight deals: it browses fares, watches prices while you're away, and brings options back for approval before it books anything.
Can Muse Do This?
Muse, Meta's personal AI agent, is well suited to fare hunting: it can browse airline and fare sites in its own browser, pull options within your budget, and keep checking after you close the app — Meta says it 'keeps working after people close the app' and comes back when something changes. Give it your route and a target price, and it can message you when a fare moves. Meta also says Muse can negotiate on your behalf, though airline fares are set dynamically and won't budge much to negotiation. What it won't do is buy without you: purchases are among the actions Muse checks with you before taking.
- Reuters reported that a flight-monitoring test inside Meta stopped refreshing during internal testing — exactly the failure mode fare-watching depends on.
- Meta's Vishal Shah has said Muse will sometimes make mistakes or fail to finish things, so verify a quoted fare before approving.
- Fares can change between Muse's snapshot and your approval; treat every price as time-sensitive.
How to Ask Muse
- 1
State the route and dates
Origin, destination, and dates — plus how flexible you are. Flexibility is the single biggest lever on price.
- 2
Set a target fare
Tell Muse the number that makes you hit 'book.' A target turns an open-ended search into a clear stop condition.
- 3
Define what 'cheap' excludes
No basic-economy traps, no two-stop routings, bags included — rules like these keep a low fare from costing you more.
- 4
Ask it to watch, not just search
Because Muse works asynchronously, ask it to re-check periodically and report back when fares move.
- 5
Require approval to book
Make the approval explicit in your prompt: options first, purchase only after you say go.
Copyable Muse Prompt
Replace the bracketed details with your own, then paste it into Muse.
Goal: Find the cheapest acceptable round-trip flight from [origin] to [destination], departing [date range], returning [date range]. Context: [Number] traveler(s). [Any must-hit events at either end — e.g., arrive before a wedding on Saturday.] Target price: [$amount] round trip, bags included. Requirements: - Max [number] stops; no red-eyes; carry-on plus checked bag included in any fare you quote. - Quote total price with taxes and fees, not the teaser fare. Actions: - Scan [the major carriers] and the fare aggregators you can reach in your browser. - Re-check fares [frequency, e.g., twice a day] and note any drop of [$amount] or more. - Come back to me when a fare hits my target or when prices move sharply. Approval: Do not purchase any ticket until I approve the exact flight and price. Output: A short list of the best fares with airline, times, total price, and why each fits or misses my rules.
Example
A freelancer in Seattle wants to visit her sister in Nashville around Thanksgiving but can leave any day in a five-day window and will pay up to $340 round trip.
I need a round-trip flight from Seattle to Nashville around Thanksgiving. I can depart any day from November 21 to November 25 and return between November 28 and December 1 — flexibility is my main lever, so use it. Target: $340 or less round trip, one carry-on and one checked bag included, max one stop, and no departures before 9am. Check the major carriers and the fare sites you can reach, and re-check twice a day between now and Friday. Message me the moment you see a fare under target or a drop of $50 or more. Do not purchase anything — when you find a match, send me the flight details and total price and wait for my approval.
What Information Should You Provide?
Date flexibility
The cheapest fares usually sit a day on either side of your first choice; tell Muse exactly how far it can shift.
Target price
A number turns 'find me something cheap' into a concrete condition Muse can watch for and act on.
Bag needs
Basic-economy fares look cheap until bags are added; stating bag count makes Muse compare true totals.
Layover tolerance
Max stops, minimum connection time, and no-red-eye rules stop Muse from surfacing fares you'd never survive.
Loyalty programs
If you bank miles with one carrier, say so — the lowest fare on a rival airline isn't always the best deal for you.
Approval and Safety
For this task, it is smart to make Muse check with you before it takes certain actions. Decide your rules up front and include them in the prompt.
Buying the ticket — Fares move fast, but the purchase is still yours to approve — Meta designed Muse to check before purchases, so keep that line active.
Adding extras at checkout — Seat selection, priority boarding, and bundles inflate the total; make Muse confirm each add-on or skip them.
Using your payment card — Prefer Link by Stripe's one-time-use card, which keeps your real card details hidden from the checkout page.
Signing up for fare subscriptions — Some fare sites push paid membership offers mid-booking; tell Muse to decline anything with recurring charges.
Tips for Better Results
- Ask for total price with bags and fees — headline fares are where cheap-flight searches go wrong.
- Have Muse re-check at different times of day; fares move, and an asynchronous agent is built for exactly that kind of patience.
- If Muse reports a fare, act quickly — it can't hold the price, and Reuters' launch reporting showed monitoring tasks can stop refreshing.
- Pair fare watching with nearby airports: give Muse two origins or two destinations and let it compare.
- When you approve a booking, double-check the passenger name matches your ID exactly — name fixes after purchase are expensive.
Find Cheap Flights FAQ
Can Muse find cheap flights?
Yes. Muse can open a browser, scan airline and fare sites, and compare total prices against your budget and rules. Meta's launch material includes booking travel among its abilities, and the agent can keep checking fares after you've closed the app.
Will Muse alert me when flight prices drop?
That's the pattern Muse's asynchronous design supports: it keeps working in the background and comes back when something changes. Set a target price and check frequency in your prompt. Just note that Reuters reported a flight-monitoring test in Meta's own trials stopped refreshing, so it's worth confirming Muse is still watching.
Does Muse book the flight for you?
Only after you approve. Filling out checkout forms is a stated Muse capability, but purchases are among the sensitive actions Meta says Muse checks with you on first. You can also require approval explicitly in your prompt.
Can Muse negotiate airfare for me?
Meta says Muse can negotiate on your behalf, but airline fares aren't really negotiable — they're dynamic prices set by the carrier. Where negotiation helps is elsewhere: refunds, rebooking after a schedule change, or customer-service disputes.
Does using Muse to find flights cost money?
Meta says Muse is free for most of what people need, with subscriptions for people who want to do more. Press reports put those tiers at $20 and $100 per month, but Meta hasn't published official pricing, and free-tier limits haven't been confirmed.
