Understanding United Airlines’ checked baggage rules before you travel can save you money, time, and last-minute stress at the airport. Whether you’re flying for business, leisure, or an international trip, knowing the size limits, weight restrictions, and baggage fees helps you pack smarter and avoid unexpected charges.
United Airlines has a standard size rule for checked bags. Each checked bag must not exceed:
62 linear inches (length + width + height combined)
This includes wheels and handles
If your bag exceeds this size, it may be considered oversized and subject to additional fees. Measuring your luggage at home can help prevent surprises at check-in.
Weight limits vary depending on your ticket type and status:
Economy & Premium Economy: up to 50 lbs (23 kg)
Business & First Class: up to 70 lbs (32 kg)
Premier elite members: higher weight allowances may apply
Bags weighing over 50 lbs may incur overweight fees, while bags over 70 lbs are generally not accepted unless special arrangements are made.
Checked baggage fees depend on your route, fare type, and loyalty status. For most domestic flights:
First checked bag: around $35
Second checked bag: around $45
Additional bags cost more and vary by route
United often charges less when you pay for baggage online rather than at the airport, so checking in early can help reduce costs.
On many international routes, United includes at least one free checked bag, especially on long-haul flights. However, baggage allowance varies by destination, cabin class, and fare type. Always check your ticket details before departure to confirm your free baggage entitlement.
If your bag exceeds United’s standard limits, additional fees may apply:
Overweight bags (51–70 lbs): extra charge
Oversized bags (63–115 inches): extra charge
Bags exceeding both size and weight limits may incur combined fees
These fees can be expensive, so redistributing items into multiple bags is often more cost-effective.
United allows certain items to be checked without extra fees in specific cases, such as:
Strollers and car seats
Mobility aids (wheelchairs, walkers)
Medical equipment (with proper documentation)
Rules may vary, so it’s best to confirm before your travel date.
