Sorry to hear about that. Most airlines offer bereavment fares that are either open ended or round trip. I think your best bet is to call a couple airlines and ask what their policy is, and get some prices. They also need to verify the event, sometimes, so they may ask you for the phone number of the funeral home, hospital, etc., so just be prepared. I don’t think you’ll have a hard time finding bereavement fares, but I know from experience that the prices are often not all that reduced. They reduce the priece of the highest priced flight they offer, so it may not be that great. But you can always call. Again, please accept my sympathy, and I hope you can make the arrangements you need to make.
