Most airlines will allow you to check one bag and have one carry-on bag. There is normally a maximum weight limit of 50 pounds per checked bag as well as a size restriction. The most common maximum size bag allowed is 62 linear (total) inches. A common size bag for checking through is: 27" x 21" x 14".

The maximum baggage allowed is governed by safety regulations and aircraft weight/balance limits. For a single checked bag, the industry-standard "heavy" limit is 32kg (70 lbs); bags exceeding this are often rejected because they pose a physical risk to baggage handlers. In terms of quantity, most airlines allow a maximum of 10 checked bags per passenger, provided you pay the steep excess baggage fees. For carry-ons, the limit is typically one bag (approx. 56x36x23 cm) and one personal item. However, for specialized "excess baggage" needs—such as moving house or transporting equipment—you must use "Cargo" services rather than standard passenger check-in. In 2026, airlines use automated scanners to ensure your total volume doesn't exceed the physical space of the overhead bin or the cargo hold, as overloading can impact the plane's center of gravity and fuel efficiency.
