United MileagePlus has logged thousands of baggage complaints across Trustpilot, the BBB, and PissedConsumer, with recurring themes around delayed reimbursements, unresponsive agents, and claim portals that seem designed to frustrate. Reviewers on PissedConsumer rate United's customer service around 1.6 out of 5, with many citing refund friction as the core issue. One BBB-verified complaint described waiting over 60 days for a delayed bag reimbursement with no updates. Your rights here are real and federally backed.

How United MileagePlus Handles Lost Baggage
Losing a bag is genuinely awful, and United MileagePlus knows it happens more than passengers expect. When your bag is lost, delayed, or damaged, you have legal protections under both DOT rules and United's own policy, not just goodwill gestures.
United MileagePlus has drawn significant criticism on review platforms. Trustpilot shows a pattern of low ratings tied to baggage handling, with users frequently citing slow responses and confusing claim portals. PissedConsumer data reflects a customer service rating hovering near 1.6 out of 5, with a notable percentage of baggage issues going unresolved on first contact. BBB records show hundreds of complaints filed against United in recent years, many specifically about delayed reimbursements and lack of follow-through.
In early 2026, United faced renewed scrutiny after a wave of social media posts highlighted baggage handling delays at major hubs. For the official policy breakdown, visit United Airlines Baggage Help.
What to Do at the Airport Right Now
Stop. Do not head to the exit yet. Find the United MileagePlus Baggage Service Office before you leave the secure area. Leaving without filing a report is the single biggest mistake passengers make, and it can seriously damage your chances of getting any compensation.
1 Refresh the United Airlines App First
Before standing in line, open the United app and check your bag status. The app sometimes updates faster than airport monitors. If it already shows your bag as delayed or misrouted, screenshot that screen. It becomes part of your paper trail.
2 File the PIR (Property Irregularity Report)
Do not leave without this. No PIR means United MileagePlus assumes you received your bag. Find the Baggage Service Office, not just any agent at the gate. Ask specifically to file a Property Irregularity Report. If an agent tries to hand you a pamphlet instead, push back.
3 Get Your File Reference Number
This is the code that ties everything together, something like ORDUA12345. A brochure is not enough. A phone number is not enough. Write the reference number down and photograph it. Without it, your online claim form will not work.
4 Request an Overnight Amenity Kit
Ask the agent directly. United MileagePlus does provide basic toiletry kits at the baggage desk for delayed bags, though agents do not always volunteer this. Some airports also offer a small clothing allowance on the spot. Ask. The worst they say is no.
5 Secure All Physical Evidence
Keep the bag tag from your boarding pass. Photograph the baggage claim ticket, the PIR form, and the signage at the Baggage Service Office. If your bag arrived damaged, photograph the damage before touching or moving anything. Blurry photos get claims rejected.
6 Verify Your Delivery Address on File
If your bag is delayed and United will deliver it, confirm the address they have on file. If you are staying at a hotel, give them the hotel address, not your home. Bags delivered to the wrong address create a whole separate headache.
7 Ask About the Interim Expense Policy
Before you walk away, ask the agent what United MileagePlus will reimburse for out-of-pocket purchases while your bag is missing. Get the answer in writing if possible, or at minimum note the agent's name and the time. This matters when you file later.
What Are Your Rights? DOT Rules and United MileagePlus Policy
This is not a favor United MileagePlus is doing you. These are legally enforceable rights under federal law.
Domestic US flights fall under DOT regulations. As of 2026, the liability cap sits at $3,800 per passenger for lost, damaged, or delayed baggage. That is the ceiling for proven damages, not a flat payout you automatically receive. You need to document what was in the bag and what it was worth.
International flights are governed by the Montreal Convention. The limit works out to roughly $1,700 per passenger, calculated using Special Drawing Rights (SDRs), which fluctuate with currency exchange rates. If you flew internationally and your bag was lost or damaged, that treaty applies.
Interim expenses are also covered. While your bag is delayed, United MileagePlus is required to reimburse reasonable out-of-pocket costs, things like toiletries, a change of clothes, or a phone charger. Keep every receipt. "Reasonable" is the operative word, so a $400 jacket probably will not fly, but a $30 shirt likely will.
For the full federal framework, see the DOT's official baggage rights page. For United's specific policy, check United Airlines Baggage Help.
How Much Compensation Can You Get from United MileagePlus?
The short answer: it depends on your route and what you can prove.
| 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) | Loss, damage, and delay up to the treaty cap |
One thing 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 the per-passenger limit. United MileagePlus can choose to pay more than the cap, but they are not legally required to. Do not count on generosity.
How to File a Baggage Claim with United MileagePlus: Step by Step
This part comes after the airport. You have your PIR, your reference number, and a pile of receipts. Now it is time to actually get paid. This process typically starts 24 hours after the incident and must be completed within 21 days for delayed bags or 7 days for damaged bags.
1 Wait for Active Status in the System
Check the United app or the baggage tracking page before filing. Submit only when the system shows your bag as Delayed, Missing, or Delivered. Filing too early can trigger a duplicate rejection that slows everything down. Weirdly, the app sometimes shows a bag as delivered when it clearly is not.
2 Find the Expense Reimbursement Form
Go to United's baggage claim page. Do not confuse the Track My Bag tool with the actual claim form. You want the page labeled something like "Out of Pocket Expenses" or "Reimbursement Request." As of early 2026, users still report this form is buried about three clicks deep.
3 Digitize Your Entire Paper Trail
Photograph your PIR, your bag tag barcode, and every receipt you have. Crop the images so text is fully legible. Blurry or cut-off photos get auto-rejected. Had to upload the same receipt three times before it stopped erroring out. Do not let that happen to you.
4 Enter Your File Reference Number
Input the code from the airport, for example ORDUA8829. If the form asks for a Ticket Number separately, that is the 13-digit number from your booking confirmation email. These are two different fields. Do not mix them up or the form will kick back an error.
5 Itemize Every Purchase Separately
Do not group items under a generic label. List each one: Clothing - T-shirt ($22), Toiletries - Toothbrush and paste ($8), Electronics - USB-C charger ($19). The system approves specific line items faster than vague totals. "Misc essentials - $60" will likely get flagged or denied.
6 Choose Electronic Payment
Select e-check or direct deposit when prompted. A mailed physical check can take six or more weeks to arrive. With a bank routing number on file, United MileagePlus typically processes reimbursements in 5 to 10 business days. Not fast, but faster than waiting for paper mail.
7 Screenshot the Confirmation Screen
The confirmation email is not always immediate. Some users report it never arriving at all. Screenshot the final Thank You screen with your Claim ID visible. You will need that ID if United MileagePlus goes quiet for a week, which, based on user reports, happens more than it should.
What If United MileagePlus Denies Your Baggage Claim?
A denial is not the end. It is frustrating, yes, but there are real next steps that have worked for other passengers.
Start by getting specifics. A vague rejection is not acceptable.
- Ask for the exact policy clause or reason code they used to deny your claim. "Does not meet policy" is not a reason.
- Resubmit with clearer documentation. Higher-resolution photos, itemized receipts, and a written timeline of events can flip a denial.
- Request a supervisor review in writing. Email creates a paper trail. Phone calls do not.
- Escalate through United's official complaint channel at United Customer Care.
- File a DOT complaint if your domestic flight was involved: DOT Air Consumer Complaint Portal. Airlines take these seriously because the DOT tracks them publicly.
- Check your credit card travel protections. Many cards, especially travel rewards cards, include baggage delay or loss coverage that kicks in when the airline falls short.
- Review your travel insurance policy if you purchased one. Baggage loss is a standard covered event on most plans.
