Each flight has specific limits on the amount of luggage permitted. Most 2010 flights allow for up to 23 kg for checked luggage (62 in), one small piece of luggage for carry-on (45 in) and one personal item.
Costs for baggage in 2010 depend on the country of departure and destination. For travel within the United States, the first checked bag is typically $25. The same fees apply if you are traveling between United States and Canada. For travel from Mexico to United States, Canada or Europe, you don't typically pay for the first two pieces of luggage checked. However, you should check with your airline directly for any changes to this policy.
Personal objects such as cameras, laptops and valuables, are among the permitted items. Restricted items include liquids, gels, and aerosols. Each container can be no greater than 3.4 ounces (see Resources). Once you are through the security gates, you can purchase and carry-on any size liquids or gels.
