Help my sisters fly home

July 2018 my father was diagnosed with neuroendocrine cancer. He was told it was incurable and was left with little options so my dad chose to do it his way. He did his best to fight his disease with the medicines our Heavenly Father put on this earth for us to use. Well, 3 years later and now his time with us is expiring. My sisters and their children live in Oregon, I am here in Wisconsin with my children, my mom, dad and my aunt Sara. We need to bring our little family together for my dad before he leaves us. He is currently on hospice in his final stages, but I think he’s hanging on for my sisters. We were raised to be more self sufficient than to ask for help so as I write this it it feels so awkward, but here we are. My little sister Keanna has a flight already booked for next week but we’re afraid he won’t have until then. My older sister Jordan is still paying on her last flight home from a few months ago when my dad fell ill before. None of us can financially afford it. Any help is greatly appreciated. Any money that is left over after we get them home will go towards funeral costs. Our hearts are all crushed right now and we just need to be together.
