My condoolences to your father's death.
I am happy for you that with the help of UA you were at least able to spend the last few hours with your dad.
As a very frequent UA flier (1K Million Miler) I have brought up critical comments on UA, e.g. during the course of this year.
It is always these special employees who really care about your concerns & thus make you keep your business with them. Happen to me on several occasions when I was about to toss my hat into the ring.
Glad to hear that UA DID WELL this time around, especially in one of your most important moments of your life.
