Carry on bag的意思

"Carry on bag" 是指可以帶上飛機的手提行李，通常是指尺寸符合航空公司規定的、可以放置在飛機客艙中的小型行李。這種行李通常需要乘客自己攜帶，不能超過規定的重量和尺寸限制，以便在飛機上放置在頭頂的行李艙或者座位下方。

Carry on bags are typically smaller than checked luggage, which is luggage that you check in at the airport and is stored in the aircraft's cargo hold. Carry on bags are often limited to one per passenger and may include a personal item such as a laptop bag, purse, or small backpack, in addition to the larger carry on bag.

The dimensions and weight limits for carry on bags can vary by airline, but a typical size limit for a carry on bag in the United States is 22 inches long x 14 inches wide x 9 inches deep, including handles and wheels. Passengers should check with their airline for specific carry on bag requirements and restrictions.
