Air New Zealand doesn't hold the trophy when it comes to poor treatment of delayed passengers.
Jet Blue is by far the worst when it comes to delayed passengers. Anytime the little gnomes get wind of major delays and cancellations they disappear into the woodwork... to avoid confrontation. No one to be found but other abandoned passengers. These little gnomes remind me of the offsprings of the Stepford Wives, or the mindless Westworld Robots.
