Something similar just happened to my sister. She had booked a non refundable flight to Atlanta to see our Mom ( 88 years old) but took out the insurance.
She and her husband had spent time on a cruise with friends and her husband had a cough. They returned home before her trip to Atlanta. Her husband was diagnosed with stage 4 lung cancer. The claim was just denied because of a pre existing cough...Are all coughs indicators of stage 4 lung cancer?
I am absolutely appalled and think that Delta should do better!!!! I will avoid flying Delta in the future if this is not resolved in my family's favor...shame on Delta!
