Airfare for Brianna to fly back for Bills funeral

As many of you know, Bill, has had a terminal brain tumor since 2013. With a heavy heart I’m letting people know that he passed away last night July 10 at the very shy age of 44. His viewing is set for Monday and Brianna is in CA with my parents and other family and needs to get back for the funeral. Normally switching an airline ticket is only a minor change but if it’s switched she’s not going back to CA because is simply not affordable. She will miss out on a trip to Disneyland with my brother and his family and cousin and her family. This poor little 11 year old just needs to have a somewhat normal, fun, summer during what is going to be a horrible year in her life. The reason we’re asking for $1200 is because my mom and I do not want to have her fly alone back here and my mom will accompany her. Airfare is about $600 a ticket
