Have a friend w/ an RDU-LHR trip planned next week and a family member is very sick and not expected to make it home from the hospital.

I'm an AA flyer so I'm not familiar enough with the CO bereavement policies to give her good advice. Can someone enlighten me as to their experiences with CO on a non-refundable ticket in the following circumstances:

a) Her family member passes prior to departure and she needs to cancel/postpone her trip.

b) His condition improves so she leaves for the trip but he psses while she's away (will they charge her a change fee to return early under these circumstances)

c) He is still with us but unimproved at the time of her scheduled trip so she cancels/postpones the trip so that she can be with the family when he does pass.

Any information would be appreciated... Thanks in advance.
