Air New Zealand Premium Economy & Biz Class Sale to London

Air New Zealand is offering seats in Premium Economy for $1,946 round-trip to London, from Los Angeles, San Francisco, and Honolulu. This sale is good for departures from now until February 29 of next year, and all travel must be booked by February 29.

We checked Air New Zealand's site for Premium Economy seats on travel from Los Angeles to London on July 19 through July 31 and found the $1,946 sale fare with no problems. That ends up being about $2,189 with taxes.

Business class along this route is also on sale, for travel now through February 29, for $3,780 round-trip. We searched Air New Zealand for business class for travel on July 19 through July 31, and found $6,203 round-trip. Since that's such a difference from the advertised sale fare, we tried June 19 through June 27 and got a fare of $5,113 round-trip, which isn't much better.

Back on ITAsoftware, we tried searching again for our original July 19 through July 31 travel dates and found that American Airlines and United both had the best price for non-stop business class for this route, at $3,088 round-trip. And for just a smidgen more ($3,108 round-trip) you could travel on British Airways.

How are the fares from Honolulu? We wish we knew. Instead we just received this message over and over: "Reservation system internal error - cannot price this itinerary, please try a different flight." Could that internal error also be the culprit behind our way-off business class fares from LA too? Air New Zealand's sale fares are generally easy to book, so we'll chalk this up to some sort of technical glitch.
