Hope you make it in time, OP, but to echo what others have said, these are not the defining moments in your relationship with your father.
When my mother died, I was at Schipol airport waiting for the connecting flight that would bring me home to her. Another couple of hours was all it needed (I lived overseas at the time, hence the travel) but it wasn't to be. At the time, I was upset - partly for myself, partly for mum but more for my dad, who was alone with her at the time.
In hindsight, though, while it sounds horrible, my being at home was more use to my dad than it could ever have been to my mum by that time. He was the one who needed help making all the arrangements afterwards, he was the one who needed someone to talk to - about mum and also, just as important at times, about 'not-mum'. Together, we got through it.
You don't mention other relatives in your post, but you won't be the only person grieving and going to your dad now means you can help others and be helped by them (as far as possible in the current circumstances). Best of luck.
