MileagePlus, United Airlines' frequent flyer program, handles baggage claims through United's baggage service system. When your bag is lost, delayed, or damaged on a United-operated flight, your MileagePlus status can influence service priority, but your core rights come from federal law regardless of elite tier. United has drawn consistent criticism on Trustpilot, where it holds roughly 1.5 stars across thousands of reviews, with baggage handling and refund delays among the most repeated complaints. BBB records show hundreds of baggage-related disputes filed against United in recent years, with many users citing slow responses and reimbursement friction. For official policy details, visit the MileagePlus Baggage Help page.
How MileagePlus Handles Lost Baggage
Losing a bag is genuinely awful. But knowing your rights upfront makes the whole process less of a guessing game.
When your bag is lost, delayed, or damaged on a United flight, MileagePlus status may bump your service priority, but your actual compensation rights come from federal law and international treaty, not airline goodwill. United is legally required to compensate you for provable losses up to set limits.
On Trustpilot, United sits around 1.5 stars, with baggage delays and reimbursement friction showing up repeatedly in reviews. PissedConsumer data reflects similar frustration, with users reporting long hold times and claims that stall without explanation. One common complaint: agents offering a brochure instead of filing a proper report. Don't accept that.

What to Do at the Airport Right Now
Stop. Do not leave the baggage claim area yet. Find the MileagePlus (United) Baggage Service Office before you exit the secure zone. Leaving without filing a report is the single biggest mistake passengers make, and it can seriously damage your chances of getting compensated.
1 Refresh the United App First
Before standing in any line, open the United app and check your bag status. The app sometimes updates faster than the baggage belt or the agents at the desk. If it shows "Delivered" but your bag isn't there, screenshot that immediately. You'll need it.
2 File the PIR (Property Irregularity Report)
This is non-negotiable. No PIR means United assumes you received your bag. Find the Baggage Service Office, not just any gate agent, and file the report in person. If an agent tries to hand you a pamphlet or a phone number instead, push back. The report must be filed before you leave.
3 Get Your File Reference Number
The PIR comes with a file reference number, something like ORDUA12345. Write it down, photograph the paper, and do not rely on the agent to email it later. This number is your entire claim. Without it, the online form won't even let you proceed.
4 Ask for an Interim Amenity Kit
United agents can provide basic toiletries or a small amenity kit at the desk for overnight delays. Not every agent volunteers this. Ask directly. Some airports have a small kit ready; others will give you a voucher. Either way, keep any receipt for anything you buy in the meantime.
5 Photograph Everything Before You Leave
Take photos of the baggage office signage, your PIR paperwork, your bag tag barcode from your boarding pass, and the baggage carousel area if your bag is visibly missing or damaged. Blurry photos get rejected later. Take them twice if you have to.
6 Confirm Your Delivery Address on File
If you're traveling to a hotel or a temporary address, tell the agent now. United will attempt delivery to whatever address is in the system. If that's your home address and you're in Chicago for three days, your bag will go to the wrong place. Fix it at the desk.
7 Note the Agent's Name and Badge Number
Sounds paranoid. It isn't. If your claim gets disputed later and the report is incomplete, having the agent's name gives you something to reference in a written escalation. Takes five seconds. Worth it.
What Are Your Rights? DOT Rules and MileagePlus Policy
This is not a favor United is doing you. These are legal obligations.
For domestic US flights, the Department of Transportation sets a liability cap for baggage claims. As of 2026, that cap is $3,800 per passenger. That's the ceiling for proven losses, not a flat payout. You have to document what you lost and show receipts. United doesn't just hand over $3,800 because your bag didn't show up.
For international flights, the Montreal Convention applies. The limit sits at roughly $1,700 USD, calculated using Special Drawing Rights (SDRs), which fluctuate with currency exchange rates. If you're flying internationally and your bag is lost or destroyed, that treaty governs what you can recover.
On delayed bags specifically, United is required to reimburse reasonable out-of-pocket expenses you incur while waiting. That means toiletries, a change of clothes, a phone charger if you needed one for work. Keep every receipt. "Reasonable" is the operative word, and United will scrutinize anything that looks excessive.
Your MileagePlus elite status does not increase these legal caps. It may speed up service, but the dollar limits are the same for everyone.
For the federal rules, see the DOT's official baggage page. For United's specific policy, check the MileagePlus Baggage Help page.
How Much Compensation Can You Get from MileagePlus?
Here's a quick breakdown of what governs your payout depending on where you flew.
| Trip Type | Governing Rule | What It Covers |
|---|---|---|
| US Domestic | DOT domestic baggage liability (up to $3,800 per passenger) | Lost, damaged, and delayed bags up to the cap |
| International (most routes) | Montreal Convention (SDR-based, approx. $1,700 USD) | Loss, damage, and delay up to the treaty cap |
A few things worth knowing: the cap is per passenger, not per bag. If you checked three bags and all three were lost, you still max out at $3,800 on a domestic flight. United can choose to pay more than the cap, but they are not required to. In practice, they rarely do without a fight.
How to File a Baggage Claim with MileagePlus: Step by Step
This part happens after the airport. Usually 24 hours to 21 days after your flight. This is where you actually get paid, not just logged. You'll be navigating United's claim portal, uploading receipts, and entering payment details. It's clunkier than it should be, but it works if you follow the steps.
1 Wait for Active Bag Status
Check the United app or website before filing anything. The system needs to show your bag as "Delayed" or confirm it's been searched and not found. Filing too early can trigger a duplicate rejection that slows everything down. Give it at least 24 hours after your flight lands.
2 Find the Correct Claim Form
Go to United's baggage claim page. Do not confuse "Track My Bag" with the reimbursement form. They're different pages. You want the form labeled something like "Out of Pocket Expense Reimbursement." As of early 2026, users still report it's buried a few clicks deep. Keep clicking.
3 Digitize Your Paper Trail
Photograph your PIR, your bag tag barcode, and every receipt you collected. Crop the images so the text fills the frame. Blurry or cut-off photos get auto-rejected. Had to upload the same receipt three times before it stopped erroring out. Not exaggerating. Take clear photos the first time.
4 Enter Your File Reference Number
Input the code from the airport (e.g., ORDUA8829). If the form also asks for a Ticket Number, that's the 13-digit number from your booking confirmation email, not your MileagePlus number. They're different. Using the wrong one stalls the form.
5 Itemize Every Purchase Separately
Do not lump things together. List each item on its own line: "Clothing - T-shirt ($22)," "Toiletries - Toothbrush and paste ($8)." The system processes specific categories faster than a generic "Miscellaneous" total. Grouping items is one of the most common reasons claims get partially denied.
6 Select Electronic Payment
Choose e-check or direct deposit when prompted. A mailed paper check can take six weeks or more. With a bank routing number, United typically processes reimbursements in 5 to 10 business days. The difference is significant if you're waiting on a few hundred dollars.
7 Screenshot the Confirmation Page
The confirmation email doesn't always arrive immediately. Some users report it never came at all. Screenshot the "Thank You" or confirmation screen with your new Claim ID visible. If United goes quiet for more than a week, that screenshot is your proof the claim was submitted.
What If MileagePlus Denies Your Baggage Claim?
Denials happen. Sometimes it's a missing receipt. Sometimes it's a vague policy clause. Either way, a denial is not the end of the road.
Here's what to do next:
- Ask for the exact reason. Request the specific policy clause or reason code they used to deny you. "Doesn't meet policy" is not an acceptable answer.
- Resubmit with better documentation. Higher-resolution photos, clearer receipts, and a written explanation of each item can flip a denial on resubmission.
- Request a supervisor review in writing. Email is better than a phone call here. You want a paper trail.
- Escalate through United's official complaint channel. Use the United Customer Care form and reference your Claim ID.
- File a DOT complaint. For US travel, go to transportation.gov/airconsumer/file-consumer-complaint. Airlines take DOT complaints seriously. It creates a federal record.
- Check your credit card travel protections. Many travel cards (Chase Sapphire, Amex Platinum, Capital One Venture X) include baggage delay or loss coverage that kicks in when the airline falls short.
- Review your travel insurance policy. If you purchased a separate policy, baggage loss is often a covered event with its own claim process.
