re: United Airlines...Good or Bad?

Couple years ago I had booked a round trip United flight to LA for a visit and my grandmother died 3 weeks prior to that date. Called them up and they changed date for $150 fee so I could now fly home sooner for funeral. What they didn't tell me was that fee is $150 PER flight. So they charged another $150 when I was flying back, even charged that twice accidentally(so now a total of $450 charged). When I called them to ask about the extra charges they ended up just waiving second set of charges all together. So they screwed up...but then I ended up coming out better because of it.
