A personal item on most airlines must fit under the seat in front of you and typically should not exceed dimensions around 18 x 14 x 8 inches (45 x 35 x 20 cm). This size is commonly accepted by airlines such as American Airlines, Frontier, and many others
. However, size limits can vary slightly by airline. For example:
- American Airlines: 18 x 14 x 8 inches
- United Airlines: 17 x 10 x 9 inches
- Air Canada: 17 x 13 x 6 inches
- Southwest Airlines: 18.5 x 13.5 x 8.5 inches
In general, the personal item must be small enough to fit completely under the seat in front of you, which is the main criterion for acceptance. Weight limits, if any, are usually between 10 and 25 pounds depending on the airline
. To summarize, a personal item can be roughly up to 18 x 14 x 8 inches, but checking your specific airline's rules is advisable since there is some variation and enforcement strictness differs among carriers
