- thanks for your very understandable question. The best answer I have on plane tickets is that you need to ask your student to look at their syllabus for each class to let you know whether the class is scheduled to meet the day before breaks. I suspect most classes will meet the day before the start of Fall or Thanksgiving break, but the faculty member may make adjustments. While the Academic Services calendar on the Registrar's website tells us the dates of breaks, individual faculty can always make adjustments on their syllabus.
The final exam schedule is also on the Registrar's calendar page, and those will tell you the dates of final exams. However, you still want to have your student consult the syllabus for each class (it could be there is not a final exam proper, but a final paper instead, etc.)
So your student should be able to tell you when they are free to leave, based on their reading of each class syllabus.
