What baggage allowance may apply on an itinerary with United Airlines?

United resolves checked-bag allowance from the actual route, travel date, cabin and membership details. Use the official trip-specific calculator, and check the first operating airline when another carrier is involved.

Important exceptions

  • A different first operating airline can apply a different baggage policy.
  • A result for one route, date, cabin or membership profile should not be reused for another trip.

What to do next

  1. Enter the real trip

    Use the actual airports and travel dates in United's checked-bag calculator.

  2. Match the booked cabin

    Select the cabin and fare shown on the reservation rather than a preferred product.

  3. Add membership details

    Enter only current, applicable traveler benefits when resolving the allowance.

  4. Check the first operating airline

    If another carrier operates the first segment, review that carrier's baggage policy before travel.
