Checking a bag for a flight to London or Tokyo used to be a simple, free affair. Not anymore. If you are looking at the United Airlines international baggage policy today, you’re basically staring at a moving target that depends entirely on your fare class, your destination, and—increasingly—the specific day you fly.
Honestly, it’s a bit of a mess.
One minute you think you’ve got a free checked bag because you’re crossing an ocean, and the next, you realize your "Basic Economy" ticket stripped that privilege away. United has become much more aggressive with these fees over the last few years. They want you to pay for the convenience of not dragging a suitcase through Newark or O'Hare. But if you know how the system is rigged, you can usually find a loophole or at least prepare your wallet so there are no surprises at the kiosk.
The Basic Economy Trap on International Routes
Most people assume that "international" means "free bags." That is a dangerous assumption. If you book a Basic Economy ticket on a flight from the U.S. to Europe or South America, your first checked bag is going to cost you. Usually, it’s $75 each way. That’s $150 round trip just to bring a suitcase.
It gets weirder, though.
If you are flying to South America or Asia, the rules shift. On many transpacific flights to places like Australia or Japan, United still offers a free checked bag even in lower fare classes, but they are constantly tweaking these "market-specific" rules. You’ve got to check the baggage calculator on their site before you click buy. Seriously. Don't trust the general vibes of the 90s when everything was included.
Basic Economy on international flights also means you don't get a full-sized carry-on for free unless you're crossing the Atlantic or Pacific. If you’re just hopping down to Mexico or the Caribbean on a Basic Economy fare, you are limited to a personal item that fits under the seat. If you show up at the gate with a roller bag, they’ll charge you the checked bag fee plus a $25 gate handling fee. It’s brutal.

Understanding the Weight Limits (It’s Not Always 50 Pounds)
Standard economy passengers are capped at 50 pounds (23 kg). If you go over by even two pounds, the fee jumps significantly. We are talking $100 to $200 extra depending on the route. It’s often cheaper to buy a second suitcase and split the weight than to pay an overweight fee on one heavy bag.
However, if you have status or you’re flying in a premium cabin, the math changes.
United Polaris, United Business, and United First passengers get a much more generous ceiling. You can pack up to 70 pounds (32 kg) per bag. And you usually get two or three of them for free. This is one of those times where the "buy up" to a better seat might actually pay for itself if you’re moving overseas or hauling heavy equipment.
- Premier Silver: 1 bag at 70 lbs.
- Premier Gold: 2 bags at 70 lbs.
- Premier Platinum/1K: 3 bags at 70 lbs.
Military members on official orders get even more—up to five bags at 100 pounds each. It’s one of the few areas where the airline is genuinely flexible.
The United Airlines International Baggage Policy for Families
Traveling with kids is already a nightmare. United makes it slightly easier by allowing you to check strollers and car seats for free. These do not count toward your baggage allowance. You can check them at the ticket counter or wait until you get to the gate.
If you have a "standard" stroller, gate checking is usually the way to go so you can use it to navigate the terminal. But if you have one of those massive jogging strollers, United might require you to check it at the counter because they simply don't have the space in the hold for a dozen giant strollers during boarding.

What about "Lap Infants"? If you're flying internationally with a baby on your lap, you are usually allowed to check one extra bag for the baby at the same rate as the adult's first bag. It’s a small mercy, but it helps when you’re carrying half a pharmacy and three weeks of diapers.
Why Your Credit Card Might Be Your Best Friend (Or Not)
The United Quest℠ Card or the United Club℠ Infinite Card can be lifesavers. They often waive baggage fees for the primary cardmember and one companion on the same reservation. But here is the catch: you must use that specific card to pay for the flight. If you use your corporate Amex but show your United card at the desk, they technically don't have to honor the benefit.
Also, these card benefits usually only apply to "standard" bags. They won't save you from the $200 fee if your bag is oversized or over 50 pounds.
High-Value Gear and "Special" Items
Are you a musician or a golfer? The United Airlines international baggage policy treats these items differently.
For example, a guitar can be carried on if there is room in the overhead bin at the time you board. If the bins are full, it has to be checked. This is why people pay for "Priority Boarding"—it's not about the seat, it's about the bin space for their expensive gear.
Golf clubs and skis are generally treated as one standard bag, provided they are in a proper travel case. If you have a boot bag and a ski bag, United usually counts them as one item as long as the boot bag only contains boots. If you start stuffing your parkas and snacks into the boot bag, they might try to charge you for two separate bags. Be smart about how you pack.

Connecting Flights and Codeshares: The Danger Zone
This is where people get burned. If you book through United but your first flight is operated by Lufthansa, Air Canada, or ANA, the baggage rules of the operating carrier might apply.
Even though you have a United flight number, the guy behind the desk at Lufthansa in Frankfurt is looking at Lufthansa's computer. Usually, Star Alliance partners have aligned their policies, but there are "service fees" and weight discrepancies that can crop up. Always check the "Operating Carrier" listed on your itinerary. If it says "Operated by Lufthansa," go to their site and double-check their specific dimensions for carry-ons. European airlines are often way stricter about the physical size of your "personal item" than United is.
Simple Ways to Beat the Fees
- Pre-pay your bags: If you know you’re checking a bag, pay for it on the United app at least 24 hours before your flight. You can sometimes save $5 or $10. It’s not much, but it’s better than giving it to the airline.
- Use a luggage scale: Don't guess. 51 pounds is the same as 60 pounds in the eyes of the computer. It's a binary "Yes" or "No" for the fee.
- Wear your heavy stuff: If your bag is at 52 pounds, take out your heaviest jacket and wear it through security. You'll look ridiculous, but you'll save $100.
- Check the "Second Bag" rule: For many international destinations, the first bag is $0 or $75, but the second bag jumps to $100 or $150. If two people are traveling, it is almost always cheaper to check one bag each than for one person to check two bags.
The Reality of Lost Luggage Internationally
If your bag doesn't show up in Paris or Delhi, United is liable under the Montreal Convention. This is an international treaty that caps their liability at roughly $1,700 per passenger.
If your bag is delayed, United will usually reimburse "reasonable" expenses like toiletries and a change of clothes. "Reasonable" is the keyword there. Don't go buy a Gucci suit and expect them to pay for it. Keep every single receipt. If the bag is truly lost (after 21 days), you have to file a formal claim with a list of every item and its estimated value.
Actionable Steps for Your Next Trip
Before you head to the airport, do these three things to ensure you aren't fighting with a gate agent:
- Check your specific "Receipt" email: United sends a link in your confirmation email called "Baggage Dimensions and Fees." Click it. It is tailored to your specific fare and status.
- Measure your carry-on: United's limit is 9 inches x 14 inches x 22 inches. They have those metal sizers at the gate. If it doesn't fit, you're paying.
- Consolidate: If you're in Basic Economy, make sure your "personal item" actually fits under the seat. If it’s a bulging backpack, they will count it as a carry-on and charge you.
The international baggage policy at United isn't designed to be friendly; it's designed to generate revenue. But with a little bit of prep and a decent luggage scale, you can keep your money for the actual vacation.
