Carry-on luggage, often referred to as hand luggage, cabin baggage, or a carry-on bag, is designed to fit in the overhead compartments or under the seat in front of you on an airplane. The exact size allowed can vary depending on the airline, but generally, there are standard dimensions that most airlines adhere to.

The weight limit for carry-on luggage can differ between airlines and countries. Generally, the weight limit ranges from 15 to 22 pounds (7 to 10 kg). However, airlines like Delta, Southwest, and JetBlue don’t have weight limits for carry-on bags on domestic flights (as long as you can lift it!). Some airlines are stricter about weight than others, so it’s essential to verify this information before packing.

Understanding the rules for carry-on luggage can save you from unexpected surprises at the airport. Here are some general guidelines:

  1. Size and weight restrictions: Adhere to the size and weight limits specified by your airline.
  2. Personal items: Most airlines allow an additional personal item, such as a handbag, laptop bag, or small backpack, alongside your carry-on luggage.
  3. Liquids: Follow the 3-1-1 rule for liquids, gels, and aerosols. Containers must be 3.4 ounces (100 ml) or less, placed in a 1-quart-sized, clear, resealable bag, with one bag per passenger.
  4. Prohibited items: Sharp objects, firearms, and other dangerous items are not allowed in carry-on luggage.
  5. Electronic devices: Ensure your electronic devices are charged, as you may be asked to turn them on during security checks.
