My sibs and I and our kids all ended up flying away to college/grad schools. We all managed fine. Back in the day, my folks had us all fly on our own, with whatever we figured we needed. It worked out. For our kids, of course, we flew up with them and helped them get settled. It gave ME peace of mind having our kids have a joint checking account with me and one of their own at the credit union on campus. We opened it when they had orientation. I’m not sure it was NECESSARY, but it was just one more way we could easily get money into their accounts. We also had a local HI bank account jointly held with each of them.
There are so many online merchants that sell things with free or low cost postage, it’s easier than ever to go to a school that is a plane ride away. Most kids are able to figure out how to navigate the airport and get on the correct plane with their gear. Most kids these days may have already flown with the family, school, sports, or other groups by the time they’re heading off for college or grad school anyway.
