United Airlines Carry-On Size Limit: The Golden Rule

Let's start with the most asked question: What is the carry-on size for United Airlines?

According to United's current policy, the maximum carry-on bag size allowed is:

• 22 x 14 x 9 inches (56 x 35 x 23 cm), including handles and wheels.

This applies to both domestic and international United flights. Your bag must fit in the overhead bin. Always check this before heading to the airport to avoid extra fees.

Personal Item Size Limit: Your Second Free Bag

In addition to your carry-on bag, United allows one personal item free of charge.
Allowed dimensions:

• 17 x 10 x 9 inches (43 x 25 x 22 cm)

Examples of personal items:

• Backpack
• Laptop Bag
• Purse
• Small Briefcase

Personal items must fit under the seat in front of you. Pro tip: If your backpack exceeds personal item dimensions, you may be forced to check it at the gate.

United Airlines Carry-On Weight Limit: No Official Cap (But…)

Here's where it gets interesting — United Airlines does not have a strict weight limit for carry-on bags on most flights! As long as you can lift your bag into the overhead bin without help, you're good to go.

Exceptions:

• If flying from select international airports (like Beijing or Shanghai), weight limits may apply (typically around 15-17 lbs or 7-8 kg ).
• Always double-check your itinerary for specific rules.

Basic Economy: Carry-On Rules Are Different!

Flying Basic Economy with United? Be careful — the carry-on rules change:

• Only a personal item is allowed for free.
• Carry-on bags are not included unless you're:
• A Premier Member
• A Star Alliance Gold member
• Holding a United co-branded credit card

If you bring a carry-on bag to the gate while flying Basic Economy without eligible status, you'll be charged a fee to check the bag — plus a handling charge.

United Airlines Carry-On vs. Checked Bag Fees: What's Cheaper?

Another frequent search query: Should I check my bag or try to carry it on?

Here's the math:

• Carry-on bag : Free for most fares (except Basic Economy)
• Checked bag : Starts at $35 for the first bag (domestic flights)

If your bag exceeds the carry-on dimensions, checking it might be unavoidable — and more expensive. That's why it's crucial to measure your luggage before your trip.

Pro Tips to Avoid Carry-On Surprises at the Airport

1. Measure at home: Always check both the dimensions and the weight (if flying internationally).
2. Use a soft-sided bag: Easier to squeeze into tight overhead bins.
3. Arrive early: Overhead space is first-come, first-served.
4. Know your fare: Basic Economy passengers need to pay for carry-ons.
