I just wanted to share this with you so you will have this info if needed one day.
Recently I had to cancel two tix due to a family funeral; one DL international and one UA domestic. Both companies promise to waive the change fee using different ways. Again I am not sure if this is possible for "any funeral" you attend or it needs to be "close family". In my case it was close family.
-DL, put the amount spent on the ticket on hold for a year, good for another ticket. The agent on the phone during the process asked me the funeral homes' name and phone number/date of the funeral and name of the deceased. She said all this info is in the computer and will pop up next time I need to make a reservation. Well, not really. First call yesterday to DL and I ended up with an agent used to work for NW ( very obvious, since she kept saying here at NW... I mean DL) and she didn't know the details, couldn't find the note under my name. After 35 minutes she said she can't waive the fee, I need to go to a DL city or airport office for that. Second phone call, this time a more competent agent, fast, tried his best but the same result. So this morning I had to go all the way to midtown NY DL office and after showing the "death certificate" and the obituary, newspaper clippings,... the $250 change fee was waived. The difference between the original ticket price and the new one is given back to me in the form of an e-voucher for future travel. Great!
-UA again put the amount on hold for a year, and told me 2 weeks before I want to book another flight mail the death certificate to their address in Chicago. Let's see how that one goes when the time comes.
I wasn't expecting this service from these companies and sure it is nice for them to go the extra mile.
I hope some people find this helpful.
