You won't get the refund unless it is a refundable ticket. However, you will get some (if not all) UA credit (in dollar amount) usable for future booking (usually within one year), minus whatever applicable fees or subtractions.

Forgot to ask if you have purchased insurance for the ticket. If yes, check if the emergency falls within the covered conditions, and you may be in luck .

Thanks a lot! I am using UA MileagePlus card, which already has trip cancellation insurance. My mom is having a serious operation in hospital, but the original flight time period is about 180 days which exceed 60 days in insurance guide... I am also not sure whether she is eligible since she is China citizen.
