Wow, indeed, true psycho to do in in Y, but you might get lucky with loads, esp. on the "new" LAX-CMN. That is unless they decide to cancel flights and then rebook pax. I did some europe-CMN-MIA connection in Y once. The outbound flight was almost full since they had cancelled (1 month out) the flight 2 days earlier but the return flight (which was evening one) had a very light load, so I could have whole row to myself.

I pray for you!
