Plz help me get 2 my dying brother

ATTENTION EVERYONE PLEASE. My Mom, Alice, and I are in desperate need of immediate help to get her from Orlando, FL to Pittsburgh, PA immediately. Her only surviving sibling, her brother,Joseph Kocher, was just diagnosed this past week with brain cancer which has already spread to his left lung and his liver which was caused by Melanoma that his doctor had misdiagnosed and had dismissed as nothing. He just came home yesterday on hospice and Uncle Joe is deteriorating rapidly and Mom needs to get there right away but the ticket from Orlando to Pittsburgh leaving tomorrow , February 4, is approximately $700. Those that know us, know that we are on a fixed Social Security income and just don't have an extra $700. Normally, I am not one to ask for help outside of prayers ,which are also desperately needed at this time, but the only thing that I can think of is to ask my extended family,friends and fellow human beings for help for my Mom. She needs to be there. I wish I could go as well so that I can be a support system for her but also because he is my only biological Uncle that I have left from both sides of my family. When you are young and surrounded by family it never dawns on you that as you get older you lose your family bit by bit until one day you are the only one left standing. Family has always been my first priority even before my own self ever since I was a kid. My Grandpa, Mom and Uncle Joe's father, is the one who taught me about family and how family sticks together through thick and thin. The older you get though the more precious family and the moments shared with them become to you especially when it's the last moments so if you could please help my Mom, we both would be eternally grateful. Thank you everyone from the bottom of my heart and soul for your help.
