MileagePlus Lost Baggage Compensation | Get Refunded

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.

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.

How Much Compensation Can You Get from MileagePlus?

Here's a quick breakdown of what governs your payout depending on where you flew.

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.

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.
