Recommendations/tips on packing for programs that are not local

<p>My son is heading to NYC for a 3 week program. Since we are flying, we are limited in the amount of stuff we can take with us. Other than buying and then tossing out most items, what do most people in these situations?</p>

<p>D just did a 3 week program with one backpack and one checked bag (max weight though!). She packed twin xl sheets, a light blanket, (too many) clothes, toiletries, etc. She bought and donated a fan and pillow, that was all she didn’t carry.</p>
