United Airlines allows a traveler to bring one carry-on item and one personal item on every flight at no additional charge. The carry-on item must be smaller than 9 inches-by-14 inches-by-22 inches, and the personal item must be smaller than 9 inches-by-10 inches-by-17 inches.
When it comes to checked baggage, United charges a fee based on the route. For instance, if flying from New York City to Los Angeles, a person pays $25 for the first checked bag and $35 for the second, as of 2015. Some people, however, do not have to pay or get a discount. These include members of the military and members of the United Club.
Those who have chosen United Economy or Premier Silver seats on United Flights are limited to a suitcase of 50 pounds, but other travelers may bring suitcases that weigh up to 70 pounds. Baggage that goes over that weight limit is subject to additional fees.
Travelers are reminded that all baggage that travels on United Airlines must go through Transportation Security Administration screening, and each traveler who checks luggage receives a claim check. At the destination airport, baggage should be picked up as soon as possible from the arrival area, and the ticket on the baggage should be compared to the claim check.
