Help Daisy get home to Dad

Daisy is my sister, six months ago we lost a brother, and 20 days ago we lost our dad. Dad died because he got COVID, and his lungs were affected by a constant cough.
My sister wants to see Dads grave. It is something that will help her in her grieving and for her to cope. I was helping her look for flight tickets to Mexico, which is where our dad lived, and the prices are very high now.  The goal is to raise the money to cover for her plane ticket. I am grateful for anyone who can and does help out. 
Dad has been a big part of our lives, as is any dad in a child's life. He was a man that talked when necessary and that was wise in many ways. Daisy and dad had a unique father-daughter relationship, and now that dad passed away it has been really hard on her. We miss dad, and we love him.
