The baggage allowance for international tours can vary depending on several factors such as the airline you're flying with, your ticket class, and your destination. Most airlines have specific baggage policies outlined on their websites or provided to you when you book your ticket.

Typically, international flights allow passengers to check at least one piece of luggage for free, with restrictions on size and weight. Additional baggage or overweight baggage may incur extra fees.

Baggage weight allowances for international travel can vary depending on the airline, ticket class, and destination. However, there are some general guidelines that are commonly followed:

1. Checked Baggage: Airlines typically allow passengers to check one or more bags without additional charges, but there are usually limits on weight per bag. The standard weight allowance for checked baggage on international flights is often around 23 kilograms (50 pounds) per bag, but this can vary between airlines.
2. Carry-On Baggage: Most airlines also allow passengers to bring one carry-on bag and one personal item, such as a purse or laptop bag, into the cabin. The weight limit for carry-on baggage is usually lower than checked baggage, typically around 7 to 10 kilograms (15 to 22 pounds) per item. However, there are also size restrictions for carry-on baggage, so it's essential to check the airline's specific guidelines.
3. Excess Baggage: If your baggage exceeds the weight limit or you wish to check additional bags, you may have to pay extra fees. These fees can vary significantly depending on the airline and the amount of excess weight or additional bags.

It's crucial to check the baggage allowance and any fees associated with excess baggage for the specific airline you're flying with, as policies can vary. This information is usually available on the airline's website or can be obtained by contacting their customer service.
