Auckland to Hong Kong ~$2230 Return in Premium Economy (1-22 Jun; 3 Jul-29 Oct 23) @ Cathay Pacific (Membership Required)

I received the following in a promotion email from Cathay Pacific

Today marks 40 years since our first inaugural flight touched down at Auckland Airport! It was in a Boeing 747-200 aircraft, fitted with 35 First Class, 36 Business Class and 337 Economy Class seats. Fast forward to today, we have three flights a week flying between Auckland and Hong Kong.

To celebrate we have an exclusive offer, the first 40 Cathay members can enjoy 40% off Premium Economy Class from Auckland to Hong Kong by entering discount code 'AKL40TH' when booking your flights.* Remember, to login to your Cathay account first for the discount code to successfully apply.

Make the most of this amazing offer and enjoy our superior inflight experience with priority boarding, spacious seats and more when you fly Premium Economy.

Please note the following:

• Membership is required, which you can sign up for free on the Cathay Pacific website
• June availability is limited and prices are a bit higher at ~$2600
• The price is 40% off Cathay pricing, but realistically, it's about $700 (~24%) cheaper than the cheapest listed Premium Economy flights on Google Flights (with one stop) or ~$1100 (~33%) cheaper than the non-stop Air NZ flight
• It says only a maximum of one adult and one child allowed per booking, but in theory, it shouldn't stop you from doing multiple bookings.
• It's a fairly decent deal to fly in Premium Economy, but if you are after cheap flights, it's still cheaper in economy (~$1300)
