Find a flight booking you forgot about
Setting Muse up as an ongoing assistant, one person on X gave it 90 days of email and calendar access, and within 24 hours it found a flight they did not know they had booked. No airline, route or date is given, so this guide covers how to make a flight booking you forgot surface.
What you can get
What it is
Flight confirmation summary
A list of any flight bookings found in your email or calendar that you had not noted, each with the airline, route, date and confirmation detail so you can verify it.
It came back right when
- Every flight reported names the airline, route, date and the specific email it came from.
- Nothing is reported as a flight without a traceable confirmation email behind it.
- No calendar or airline change is made without your separate approval.
- You have independently checked at least one reported flight against the airline before trusting the rest.
The checks are editorial, not from the source.
- Set scope and windowStops for your approval
Mailbox, calendar and time window to search.
- List every confirmation found
Airline, route, date, confirmation number, source email for each.
- Verify against the airlineStops for your approval
You check at least the key findings directly before trusting the rest.
- Decide what to do with it
Add to calendar, check in, or flag for follow-up, on your approval.
Editorial, not from the source
Works when
- You suspect something was booked and forgotten, or want to double-check before a trip.
- You are comfortable giving read access to your mailbox and calendar for the search window.
- You will verify any flight found against the airline directly.
Does not work when
- You need it to also check in or manage the flight; this report covers finding it, not acting on it.
- Your bookings live in an account or app the mailbox search cannot see (a travel agent's portal, for instance).
- You are not comfortable granting broad mailbox read access for the search.
Find a flight booking you forgot about: review template
| Item | What it is based on | Status |

| Flight found (airline/route/date) | Source email subject and date | Verify |
| Confirmation number | Email it was found in | Verify |
| Current status | Airline response | Confirmed/Pending |
The source case
On X, @andr3barroso describes giving Muse broad access to 90 days of email and calendar as part of setting it up as an ongoing assistant, and reports that within 24 hours it found a flight the poster did not know they had booked, among several other results like reviewing a French email and setting birthday reminders. The post includes the setup prompt used but does not name the airline, route, date, or how the flight was confirmed, and does not say what would have happened if the flight had gone unnoticed. This is one attributed post, checked on 2026-10-09, describing a side effect of a broader assistant setup rather than a task run on its own.

Source excerpt
scanned 90 days of email + my calendar — and found a flight I didn't know I'd booked
Quoted from the original posts. Not written by this guide, and not a result produced here.
Suggested prompt
Bring Mailbox and calendar access, A search time window. Acts Reads the mailbox and calendar you connect. Does not change or cancel anything; it only reports. Source community report, checked 2026-10-09.

What you need
Editorial, not from the source
You supply
- Mailbox and calendar access
- A search time window
Connected
- The email account that receives booking confirmations
- The calendar you want checked against it
Approved by you
- Read-only access is enough for this task
- No authorization to change or cancel a booking it finds
How to try it
Editorial, not from the source
- Give it read access to the mailbox and calendar you want searched, and a time window.
- Ask it to list every flight confirmation found, with airline, route, date, confirmation number and the specific email it came from.
- Check each result against the original confirmation email yourself before assuming the flight is real or current.
- If a flight is found, decide whether to add it to your calendar, and confirm seat, check-in or payment status directly with the airline if anything looks off.
This was a side effect, not a dedicated search
The report behind this task comes from someone setting Muse up as a broader assistant with 90 days of email and calendar access, not from someone specifically asking it to look for a forgotten flight. Within 24 hours it surfaced a flight the poster says they did not know they had booked, alongside unrelated results like a French email review and birthday reminders. If your goal is specifically to check for a missed booking, say so directly rather than relying on a wide assistant setup to surface it as a byproduct; ask for every flight confirmation in the window, named individually, rather than a general summary of what it noticed. Treat a result that surfaces this way as a lucky find, not as proof the search was thorough across every mailbox folder.
Give it the right window and the right access
A forgotten booking could be recent or months old, so state the time window explicitly rather than leaving it open-ended; the source post used 90 days of email alongside the next 30 days of calendar. Searching that much mail means granting real read access, so decide in advance whether that scope is acceptable for the account involved, and whether a narrower, trip-specific mailbox or folder would do the job with less exposure. None of this was tested here against a known missing booking, so there is no report of how reliably a 90-day window surfaces every confirmation versus only some of them. State the window in both directions, so a date far outside it is not silently excluded, and say explicitly whether a connected but unused calendar should also be checked.
Confirm before you act on what it finds
A flight confirmation sitting in an old email is not the same as a flight that is still happening as booked; airlines cancel, reschedule and consolidate flights, and a confirmation from weeks ago may no longer be accurate. Once something is found, check it against the airline directly, by confirmation number, before adding it to a calendar or treating it as settled. The attributed post reports that a flight was found, not that its current status, seat, or check-in requirements were checked, so build that step in yourself rather than assuming the discovery is the end of the task. If nothing turns up, that absence is not proof nothing was missed either, since a confirmation sent to a different address or app would not appear in this search at all.
Open Muse to try it. That is the product's own site; this guide is not part of it.
Limits and confirmation points
Limits to confirm
- This is one attributed post reporting that a forgotten flight booking was found as a side effect of a broader 90-day email and calendar review; it does not name the airline, route, date or how the finding was confirmed.
- A flight confirmation email can be out of date (changed, canceled, or already flown) by the time it is found; check current status with the airline rather than trusting the email alone.
- Searching 90 days of email and calendar requires broad read access; decide in advance whether that scope is acceptable.
Stop and check
Editorial, not from the source
- Before it searches: confirm the mailbox, calendar and time window in scope.
- When it reports a flight: check the result against the original confirmation email.
- Before you rely on it: confirm current status (not canceled or changed) directly with the airline.
If it goes wrong
Editorial, not from the source
- It reports a flight with no confirmation email attached
- Treat it as unconfirmed until you can locate the original email yourself; do not act on a result without a traceable source.
- The flight it found was already canceled or changed
- Check current status directly with the airline using the confirmation number; an old email does not reflect later changes.
- It misses a booking you know exists
- Check whether that confirmation sits outside the time window searched, in a different mailbox, or in an app rather than email, and widen the search accordingly.
Common questions
Can this find every flight booking I have forgotten about?
Not guaranteed. The one report behind this task found a flight as a side effect of a broader 90-day email and calendar review; it does not establish how reliably every booking type is caught.
How much access does it need?
Read access to the mailbox and calendar for the time window you set. The source used 90 days of email and 30 days of calendar; narrow this if you are not comfortable with that scope.
Will it check in or manage a flight it finds?
Not based on this report. It names what it found; checking in, changing or canceling is a separate task with its own approval.
What if the flight it finds was already canceled?
Confirm current status with the airline using the confirmation number. An old email does not reflect later changes to the booking.
Is this a tested search process?
No. It is drawn from one attributed post where the finding was a byproduct of a broader assistant setup, not a dedicated, repeated search.
