@Am1432,
- No fees apply because of your age.
- Luggage fees depend on the airline, but $25/bag is typical with the bag weigh not to exceed 50lb.
- You will likely have a connecting flight and will want to have money to get food during the connection.
- If you have a ride to and from the airport, you will not need taxi fees, but if you do need a ride, you should research how much that will be. It can be expensive depending on how far from the airport you are.
