A friend is currently at LAX at 00:30 on a EWR-LAX-AKL-MEL journey on an NZ issued ticket. The UA flight to LAX was delayed 4+ hours in NYC and the connection on NZ to AKL was missed. There are no NZ reps around and one solitary UA person trying to deal with a lot of people lined up. He has no status and is in Y. UA is responsible for looking after him overnight? The next NZ flight is in 21 hours.
