International checked-bag allowances and charges vary by origin, destination, cabin, fare, status, operating carrier, and ticket date. Use United's official bag-fee calculator for your itinerary rather than carrying a transatlantic or transpacific price from this page into checkout.
Overweight, oversized, and special items
Do not rely on a single excess-bag table: acceptance and charges vary by route and item, and multiple charges can apply. Enter the flights in United's baggage calculator, then review the separate sports-equipment or assistive-device policy if relevant.

Tips & Tricks
Booking:
- Book directly on united.com for best rebooking support during disruptions
- Compare Basic Economy using the exact carry-on allowance and restrictions displayed for your route
- Do not assume a United card changes the allowance unless the reservation reflects the qualifying benefit
- Use the Baggage Calculator to see exact fees before booking
At the Airport:
- App check-in is fastest—avoid counter unless checking bags
- ORD: Terminal 1 only; allow 20+ min for distant gates
- EWR: Terminal C has three concourses; watch connection times
- SFO: International gates in Terminal G require extra walking time
- Polaris Lounges are worth arriving early for (ORD, EWR, IAH, SFO, LAX, IAD)
Upgrades:
- Complimentary upgrades clear based on status: 1K at 96 hrs, Platinum at 72 hrs, Gold at 48 hrs, Silver day-of

- Connection times under 60 minutes at ORD/EWR are risky during peak hours
