United Airlines has clear baggage weight restrictions for both carry-on and checked luggage. For checked bags in economy, the limit is 50 lbs, with a maximum size of 62 inches (length + width + height). If your bag exceeds the weight or size limit, you’ll face additional fees, so it’s best to weigh and measure your bags before heading to the airport. Premium cabin passengers enjoy higher limits, with checked bags weighing up to 70 lbs. https://www.flightaura.com/baggage-policy/united-airlines-baggage-policy/
