The girl who was going to be on the plane got off at the last minute and because of the delay the plane was re-checked and a problem was found so the plane never took off and there was no crash. Eli lived but the young lady who's case he was involved in died. Her organs were saved and her heart went to Grace, the character played by Katie Holmes earlier in the season, but we never saw her, we just heard about it. At the end Eli had a vision of himself with his father at the Himalayan mountain they keep referring back to and they talked for a bit but I don't remember the exact nature of their conversation. There wasn't really any sort of complete wrap up to the show, it just sort of ended after Eli and his dad talked and he found out the heart went to Grace and I think the last scene was him back at his office.
