United's baggage policy is based on your ticket type, route, and status. Most fares permit one free carry-on and a personal item. Checked bags typically have a 50 lb (23 kg) limit for Economy, requiring a fee, but are free and 70 lb (32 kg) for premium cabins and elite members. Basic Economy may exclude a free carry-on.
