Don’t have much to add to the tips above except that I would advise booking holiday flights as soon as you find out the finals schedule. We also tried to have our daughter have layovers (there was no direct flight between her city and our city) in cities where either she knew someone or we knew someone in case she was stranded with a holiday storm or cancellations. Also good to check with your health insurance. Any time there is a medical situation that is not handled by the student health center, you could incur out of network charges. Some insurance policies have a “student out of network” medical deductible that is different from regular out of network (which can be $$$$$).
