To piggy back on @mamom”s post, don’t. Forget the cost of getting to/from the airport, luggage fees, food money or additional money if there is a delay/cancellation.
Also keep in mind if your child gets a scholarship for a specific amount of money (8k, 10k, 20k/year) the scholarship will not increase as the cost of tuition increases. If your child receives a half tuition/full tuition scholarship, the scholarship will increase as tuition cost increases
