CHICAGO — American Airlines says security video footage proves a woman in a wheelchair was not left alone overnight at Chicago’s O’Hare.

Olimpia Warsaw, 67, is described as having Parkinson’s disease, diabetes, and has difficulty communicating. She was flying from Chicago to Detroit on Friday, Nov. 30, after attending her ex-husband’s funeral.

When Warsaw’s flight was canceled, family members said she sat alone in her wheelchair and was unattended for five hours until a relative came to pick her up.

Her son Claude Colteau told the Chicago Sun-Times his “mother was found in a dark hallway near a restroom, where another passenger had taken her upon request.”

An American Airlines spokesman previously said the airline met with the family, refunded Warsaw’s ticket and was taking steps to “ensure this does not happen again.”

But after launching an investigation, the airline is proving the family’s story does not add up.

American Airlines released a timeline of the incident to WGN News after reviewing camera footage, call records from the wheelchair attendant’s phone and reservations call records.

The timeline shows approximately 45 minutes elapsed between the time the wheelchair attendant left Warsaw and her relative came to pick her up.

The timeline also shows that Warsaw used a walker to go outside to smoke a cigarette on two different occasions.

There’s no word yet from the family after the airlines released its timeline.
