(WBIR) A charity organization is helping a Knoxville woman get to her out-of-state doctors appointments for free.

Pilot Bob Anderson flew Angie Perkins and her husband from Knoxville to North Carolina on Saturday using his private plane.

Anderson is part of LifeLine Pilots, a group based out of Illinois that flies patients for free to and from places where they are receiving medical care. The pilots incur all the costs associated with the trips but sponsors and donations help as well, according to Anderson.

Saturday's flight was one of several trips he's taken to help Perkins get to her specialized care at Duke University Hospital in Durham, North Carolina.

Angie's husband said this service is crucial to his wife getting the care she needs. She's dealt with many serious medical issues over the years and has flown with LifeLine Pilots more than 20 times since 2011.

"What they allow us to do by taking us back and forth to get the medical needs done, I mean it's literally saved her life......and I can't thank these guys enough," Tommie Perkins said.

LifeLine Pilots also helps take people who are going to be organ donors to their destinations.
