It’s about $100 each way for UM and most pre-college programs will not meet them at the gate which is what is required for UM travel. It’s so stupid. The smaller airlines allow younger travelers and we have used that extensively.
Agreed on the $2400 cost. My D not only signed up for a CTY course (3 weeks/$1000) but a FREE Harvard course and 2 UChicago courses that had nominal fees. She’s going to be busy now.
