We are taking a charter flight from SJU to EIS and back, so the only places that I could see us possibly being asked for the consent forms are entering the BVIs and returning to the US. Possibly the air charter but nothing from them yet hinting at that. Our airline flights are all domestic so I don't expect any issue in that regard. I guess I'll probably send each parent a form and ask them to get it notarized and see what response I get.

Thanks!
