When Ben and Michaela go to the Vasik's home, their children are not old enough to have been all been alive or needing reminders of sunscreen when their parents took flight 828. If flight 828 was at least 5 1/2 years ago, the children should all be in the 6-12 age range.
When Ben and Michaela go looking for the Vasiks they go over the GW Bridge, taking them into New Jersey. When they save the family that had gone over the cliff, the responding personnel, fire and police, were all from NYC.
When Ben tells Michaela about the Bible verse the Vasiks had on their wall, he calls the Book in which it appears "Revelations" instead of the singular "Revelation".
