Is it safe to post your boarding pass on Instagram?
A boarding pass next to a coffee or a passport is a classic travel post. But that small barcode carries more than the destination you want to show off.
The short answer: no. The barcode and the printed text on a boarding pass contain your full name and booking reference. On many airline websites, those two are enough to open your booking, see your details and change or cancel your flights. The barcode often adds your frequent flyer and ticket numbers. Blurring your name isn't enough: crop the pass out, or share a photo without it.
What a photo gives away
Here's a fictional pass. Everything outlined can be read from a sharp photo, either from the print or by scanning the barcode with any phone.
Booking reference, name and the barcode are the parts that matter.
The barcode holds more than the print shows. Following the airline industry's boarding pass barcode standard, it typically contains:
- Your full name as it appears on the booking, often with a title.
- Your booking reference (PNR), the key to your reservation.
- Flight number, route, date, seat and booking class.
- Your 13-digit e-ticket number.
- Your frequent flyer program and number, if you added one.
- How and when you checked in, your baggage allowance and security flags.
It does not normally contain your passport number, address or payment details. The problem is what the booking reference unlocks.
What someone can do with it
Airlines let you manage a booking online with just your surname and booking reference, with no password. That convenience is also the weak spot: anyone who has both can usually do the same. Depending on the airline, a stranger could:
- See your booking, including the rest of your itinerary, other passengers on the same reservation, and often your e-mail address or phone number.
- Change your seat, meal or other services, or add a different frequent flyer number so someone else earns the miles.
- Cancel or change flights, including your return trip.
- Send you a convincing scam. A message that knows your name, flight and seat ("Your flight LH 714 was cancelled, rebook here") is far easier to fall for.
- Know when you're away. A pass with dates tells anyone following you how long your home will be empty.
It has happened to a former prime minister. In 2020, former Australian prime minister Tony Abbott posted a photo of his boarding pass on Instagram. A security-minded reader used the booking reference to log in to the airline's booking page and found Abbott's passport number and phone number in the page's data. He reported it to the airline, which fixed the issue, but it shows how much a single photo can expose.
"But my flight has already landed"
Posting afterwards helps less than you'd think. Bookings usually stay visible online for a while after the trip. On a round trip, the outbound pass shares its booking reference with your flight home. Your name, frequent flyer number and ticket number don't expire.
How to share your trip safely
The wing at sunset, the gate, the departures board. It says "I'm travelling" just as well.
Remove the barcode and the printed booking reference, not just your name.
If you must show it, cover both with an opaque shape. Don't rely on blur or stickers.
Waiting until after the trip removes the "empty house" signal and the return flight risk.
Barcodes have built-in error correction. A light blur or a partly covered code can still scan.
The square code on an app or Apple Wallet pass holds exactly the same data as the paper version.
The same goes outside of social media. Don't leave paper passes in the seat pocket or in a hotel bin, and remove old passes from Apple Wallet once you've landed. Your bag tags also carry your name and sometimes your booking reference, so take them off before you throw them away.
Already posted it?
- Delete the post, and check story archives, highlights and anywhere you cross-posted it.
- Check your booking on the airline's website for changes to seats, flights, contact details or frequent flyer number.
- Secure your frequent flyer account with a strong, unique password, and turn on two-factor authentication if it's offered.
- Watch for scams. Contact your airline only through its official app or website, never via links in unexpected messages about your flight.

FAQ
Is it safe to post my boarding pass after the flight?
Not really. The booking usually stays accessible online for weeks or months, and on a return trip the same booking reference covers your flight home. Your name, frequent flyer and ticket numbers don't expire either.
Is it enough to blur the barcode?
Not reliably. Barcodes are designed to survive damage, and a light blur or a partly covered code can often still be scanned. Crop it out or cover it completely with a solid shape, and hide the printed booking reference too.
What can someone do with my booking reference?
On many airline websites, the booking reference and your surname are enough to open the booking. Depending on the airline, that can show your contact details and itinerary and allow changing seats, adding a frequent flyer number or cancelling the flight.
Is a screenshot of a mobile boarding pass just as risky?
Yes. The square Aztec or QR code on a mobile or Apple Wallet pass holds the same data as the barcode on a paper pass.
I already posted my boarding pass. What should I do?
Delete the post, including from story archives and other platforms you shared it to. Log in to your booking and check that nothing was changed, secure your frequent flyer account with a strong password, and be suspicious of messages that mention your flight.
