By fare / bag product

What you can bring often depends on the ticket—not only the airline name. Re-check United Airlines's baggage page (last checked 2026-08-30).

  • Basic / lowest fare: Basic Economy often restricts carry-on; verify route/fare before departure.

How Airlines Calculate Luggage Size

Airline baggage limits in inches are based on the outer box dimensions of your bag, not volume.

  • Carry-on rule (most common): single-side limits such as 22 x 14 x 9 in (L x W x H).
  • What must be included: wheels, handles, feet, and any rigid external parts.
  • What is not used as the main rule: liters/cubic volume is usually not the acceptance criterion.
  • Sizer logic at airport: if the bag does not fit the frame, it can be denied or gate-checked.
