You can get a United Airlines boarding pass online, through the United app, at an airport kiosk, or from a United check-in agent. Checking in before you leave home is usually the easiest option, but document checks, partner-operated flights, and airport-specific rules can sometimes require in-person help.
Quick Answer
United Airlines check-in normally opens 24 hours before departure. Enter your confirmation or eTicket number and last name at united.com, or check in through the United app. You can then use a mobile boarding pass, select a home-printing option when available, or request a paper pass from an airport kiosk or agent.
Key Takeaways
- United normally opens online and app check-in 24 hours before your scheduled departure.
- You need your last name and either a United confirmation number or an eligible eTicket number.
- A paper pass may be printed at home when the print option appears, at an airport kiosk where available, or by a United agent.
- The United app can store your pass and may let you add it to Apple Wallet or Google Wallet.
- International document checks, partner flights, airport restrictions, or reservation issues may prevent an immediate mobile or printable pass.
- Do not wait until the last minute. Minimum check-in and bag-drop times vary by airport and destination.

At a Glance
| Time Required | About 5–10 minutes when your reservation and documents are ready |
| Difficulty | Easy |
| Tools Needed | Confirmation or eTicket number, last name, internet-connected device, and an optional printer |
| Cost | United does not normally list a separate charge for accessing or printing its boarding pass; third-party printing services may charge their own fee |
What You’ll Need
Gather these details before you begin:
- Your United confirmation number, usually a six-character code found in your confirmation email or trip details
- Your last name exactly as entered in the reservation
- Your eTicket number if you do not have the confirmation number; United-issued ticket numbers are 13 digits and normally begin with 016
- Your passport or other required travel documents for an international itinerary
- A phone, tablet, or computer with internet access
- A working printer if you want to print at home
- The United app if you want to use a mobile boarding pass
Estimated time: Online check-in and boarding-pass access usually take about 5–10 minutes when no document or reservation issue needs review.
Warning: Online check-in opening 24 hours before departure does not mean you can check in until boarding begins. For most United-operated flights within the United States, check-in must be completed at least 45 minutes before departure. Some airports and international routes have earlier deadlines, so verify the requirement shown for your itinerary.
How to Access Your Boarding Pass
United online check-in normally opens 24 hours before scheduled departure. You can check in without a MileagePlus account.
Check in on the United website
- Open United’s official check-in page.
- Enter your confirmation or eTicket number.
- Enter the passenger’s last name.
- Review each passenger and flight included in the reservation.
- Confirm or update required travel details.
- Add checked bags or review available seat options when needed.
- Complete check-in.
- Select the available mobile, email, download, or print option.
If you booked through a third party, use the United confirmation number supplied for the United-operated portion of the trip. A travel agency may display its own booking number separately.
Check in through the United app
- Open the United app and sign in to MileagePlus, or select the option to find a trip.
- Enter your confirmation number and last name if the reservation is not already saved.
- Open the trip and select Check in.
- Review the passenger, seat, baggage, and document information.
- Complete check-in and open the boarding pass.
Pro Tip: Check in early enough to resolve document or reservation problems, but do not assume that checking in at exactly 24 hours guarantees a preferred seat. Seat availability depends on your ticket, previous selection, status, aircraft, and remaining inventory.
Check the operating airline
Look at the words “operated by” in your itinerary. If another airline operates the first flight, you may need to check in through that airline rather than United. The operating carrier may issue some or all of your boarding passes.
Printing Your Boarding Pass at Home
After completing check-in on United’s website, look for a Print boarding pass, View boarding pass, or downloadable document option. The exact buttons may vary by browser, itinerary, and current United website design.
- Open the boarding pass after check-in.
- Select the print or downloadable-file option.
- Open the browser print window or downloaded document.
- Choose the correct printer and standard paper size.
- Print at normal scale unless the preview cuts off part of the barcode.
- Check that the passenger name, flight number, date, and barcode are readable.
Black-and-white printing is normally sufficient when the barcode is sharp and complete. Avoid draft-quality settings, streaked ink, creases through the barcode, or resizing that cuts off part of the pass.
Note: A home-printing option may not appear when United or another airline needs to inspect your passport, visa, destination documents, identity, or reservation at the airport. This does not always mean your booking has a problem.
Before leaving home, compare the passenger name with the reservation and identification. Correct a meaningful spelling, identity, or passenger error as soon as possible. Minor suffix differences, such as a boarding pass showing “Jr.” when an ID does not, are generally accepted by TSA, but airline and international document rules can differ.

Printing Your Boarding Pass at the Airport
| Method | What You Need | Best For | Important Limitation |
|---|---|---|---|
| United self-service kiosk | Confirmation number, passport, eligible ID, or another identification method offered by the kiosk | Routine check-in and reprinting | Kiosks are not available at every airport and may direct you to a digital pass first |
| United check-in counter | Government-issued ID and required travel documents | Document checks, reservation problems, special assistance, or kiosk failures | Lines and counter closing times vary |
| Partner-airline counter | Operating-airline confirmation and travel documents | Trips whose first flight is operated by another airline | United may not be able to issue every partner boarding pass |
| Airport or hotel business service | An emailed or downloaded printable pass | Travelers without a working home printer | The third-party service may charge a printing fee |
Where a United kiosk is available, follow the on-screen instructions to locate your reservation. Some kiosks emphasize mobile or emailed passes first, so look for a button such as More options if you specifically need paper.
If the kiosk cannot complete the process, take your identification and travel documents to a United agent. An agent can check the reservation, review documents, assist with eligible seat or baggage changes, and issue a paper pass when permitted.
Warning: Arriving at the airport before departure is not enough by itself. You must meet the applicable check-in, baggage-drop, security, and boarding deadlines. Airport queues do not normally extend those deadlines.

Using the United Airlines Mobile App for Boarding Passes
The United app lets you find your trip, check in, view your boarding pass, monitor flight details, and receive operational updates. After check-in, open your trip and select the boarding-pass button.
When the option is available, add the pass to Apple Wallet or Google Wallet. A pass saved to a supported wallet is easier to reach and can normally be opened without an active internet connection.
Before reaching a scanner:
- Charge your phone.
- Turn up the screen brightness.
- Open the correct passenger and flight segment.
- Remove anything covering the barcode.
- Keep the screen steady until the scanner confirms acceptance.
Pro Tip: Save the pass to your phone’s supported wallet while you still have internet access. Do not rely only on airport Wi-Fi or a last-minute app login.
Gate, boarding time, aircraft, and seat information may change after the pass is issued. Continue checking the United app, airport displays, and announcements rather than relying only on information printed earlier.

When a Boarding Pass Is Not Available
You may complete part of the online check-in process without receiving a usable boarding pass. Common reasons include:
- United needs to inspect a passport, visa, residence permit, health document, or destination entry document.
- Your trip begins with a flight operated by another airline.
- The departure airport or operating airline does not accept mobile boarding passes for that flight.
- A passenger requires an identity, age, special-service, or security review.
- The reservation was changed, reissued, or booked through an agency and needs additional processing.
- A seat has not yet been assigned.
- A system or app error prevents the pass from loading.
For international trips, review the requirements in United’s Travel-Ready Center. Uploading or reviewing documents in advance may reduce airport processing, but an agent can still require an in-person inspection.
Note: A message telling you to see an airport agent does not automatically mean the ticket is canceled. Arrive early with your identification, passport, visas, and any other required documents.
Troubleshooting Common Issues with Boarding Passes
United cannot find the reservation
Confirm that you entered the United confirmation number rather than a travel agency’s reference. Check every letter and number, then enter the last name exactly as it appears in the reservation. You can also try the eligible 13-digit eTicket number.
The print option is missing
Return to My trips, open the reservation, and look for boarding-pass options. Try a current browser, allow pop-ups for united.com, and check whether a document-review message appears. When printing remains unavailable, use a supported mobile pass or request help at the airport.
The United app says you are checked in but shows no pass
Close and reopen the trip, check the app’s check-in or boarding-pass menu, and confirm that you are viewing the correct flight segment. Then try united.com in a browser. If the pass was previously saved to Apple Wallet or Google Wallet, check there. Otherwise, use a kiosk or ask an agent to print it.
The barcode will not scan
Raise the screen brightness, clean the screen, remove display overlays, and make sure the full barcode is visible. For paper passes, flatten folds and print a new copy if the barcode is streaked, faded, or cut off.
The boarding pass has no gate or seat
A gate or seat may not be assigned when the pass is first issued. Check the app and airport displays later. If your seat remains unassigned near boarding, speak with the gate agent.
The passenger name looks wrong
Contact United or the ticketing agency when the pass shows a meaningful spelling error, the wrong passenger, or a name that does not correspond to the travel document. TSA accepts some suffix variations on U.S. trips, but that does not cover major name differences or international document requirements.
Warning: Do not post a boarding-pass photo online or send the full barcode and confirmation number to people who do not need them. The pass can expose personal and booking information.
Benefits of Preparing Your Boarding Pass in Advance
Checking in and preparing your pass before leaving home can reduce the number of tasks you need to complete at the airport. Passengers traveling without checked bags or required document checks may be able to proceed to security after confirming that they have a valid pass and the required identification.
Advance preparation does not let you skip checked-bag drop, document inspections, security screening, or airport-specific procedures. It simply helps you identify problems while there is still time to resolve them.
A paper copy can also serve as a practical backup if your phone battery dies, your app fails, or your screen is damaged. A saved mobile pass is useful when the printed copy is lost or becomes unreadable. You do not need both formats, but carrying a backup can reduce stress during disruptions.
Frequently Asked Questions
What is a United Airlines boarding pass?
A boarding pass is the document or digital pass issued after check-in for a specific flight. It normally includes the passenger name, flight number, travel date, boarding information, and a scannable barcode. A gate or seat may be added or changed later.
How do I print a United Airlines boarding pass at home?
Check in at united.com beginning 24 hours before departure. After check-in, open the boarding-pass options and select the available print or downloadable-document option. Print the entire pass at normal scale and confirm that the barcode is sharp and complete.
Can I print my United Airlines boarding pass at the airport?
Yes. Where available, use a United self-service kiosk and look for the paper-printing option. A United agent can also issue a pass when the reservation and travel documents meet the requirements. Partner-operated flights may require the operating airline’s kiosk or counter.
Do I have to print my United boarding pass?
No. A mobile boarding pass in the United app, Apple Wallet, or Google Wallet is normally sufficient when the departure airport and operating airline accept mobile passes. A paper pass may still be required or more practical for certain airports, document checks, partner flights, or technical problems.
Can I add a United boarding pass to Apple Wallet or Google Wallet?
Yes, when the relevant save-to-wallet option appears after check-in. Open the boarding pass in the United app or supported webpage, select Apple Wallet or Google Wallet, and follow the device instructions. Availability can vary by device, country, flight, and itinerary.
Why did United let me check in but not give me a boarding pass?
United or the operating airline may need to inspect travel documents, verify identity, review the reservation, assign a seat, or complete another airport process. Follow the message in the app or website and arrive early enough to visit the correct check-in counter.
Can I use a screenshot of my United boarding pass?
A clear screenshot may scan in some situations, but the United app or a supported wallet is safer because it can retain the complete pass and display updated information. Do not rely only on a screenshot when the airport or itinerary requires a live mobile pass or document review.
What should I do if my phone dies at the airport?
Use a kiosk where available or take your identification and travel documents to a United agent or the operating airline’s counter. The agent can locate the reservation and issue a paper pass when check-in is still open and the reservation is eligible.
Check in with enough time to review the passenger name, flight date, operating airline, and travel-document requirements. Save the pass to your phone or print it when that option is available, and continue monitoring the app or airport displays for gate, seat, and schedule changes.
