Airline ticket for my mom

My mom is a newly diagnosed for pancreatic cancer metastasized to the liver but when we found out it was stage 4 already. I brought my mom to Memorial Sloan Kettering Cancer Center. They offered her for chemo but it's not guaranteed that it will help her extend her life. My mom refused chemo. She said that she rather enjoy the rest of her life with the families. She has 3 wishes: she doesn't want to feel the pain which is under control with medications, she wants to go to church & she wants to go back to the Philippines. It's almost 24 hrs going there. I want to buy an airline ticket but it's a little bit expensive because I want to put my mom in the business class so that she could lay down during the flight. Hopefully she is able to relax and not able to think about the long flight. I really appreciate it if you could help us with it. Thank you in advance.
