Alice Peacock flies Premium Economy with United Airlines on UA917, from San Francisco to Auckland.
The plane: A Boeing 777-300ER.
Class: Premium Economy.
Price: $3737 Auckland to San Francisco Premium Economy return.
My seat: This was my debut in Premium Economy, and the sight of a bigger seat with extra leg room ahead of a 12hr 50min flight was sweet relief. Seats in Premium Economy have La-Z-Boy-esque footrests to make the most of that stretching room, as well as bigger trays and deeper seats.
