United transfering through LAX

[Jack B]

Hi all,

For those with experience - how long would you say is a safe time between flights when transferring with United through LAX?

When I enter SYD-JFK flights into Webjet, one option (Which is by far the cheapest) involves getting off UA840 at LAX at 10:15am, and onto UA416 at 11:25 am.

Is this too short a time? If, say, UA840 was late and I missed 416, would United put me onto another flight?
