I bought some tickets from Seattle to Melbourne, Australia back in November for next month, and they changed the flights. When I entered my passport number into Qantas I noticed they changed my flights so that I only have a 40 minute layover in LA before I connect to my flight to Melbourne.

Will this be enough time? I've never actually been to LAX before so I don't know the layout, nor have I ever had that short of a layover so I'm not sure if my bags will make it.

I'm thinking about either calling Qantas to reschedule, or just going and buying some insurance on my bags in case they get lost if they don't make it with me (if I make it at all).
