These are daily specials on the website of New Zealands' major airline, and they give you opportunities to travel in a fun, spontaneous, and incredibly affordable way. How affordable? Try between $29 and $59 one way, most or all taxes in.
How this works is like this: every day, early in the morning, Air New Zealand makes a fixed number of seats available for specific routes, in specific date ranges. Once these seats sell out, your outta luck -- so needless to say, it's been a part of my morning work routine to check the daily deals.
Usually it's domestic flights on sale, but every once in a blue moon, there's a fantastic international special. One time, Wellington to Tokyo was on sale for $450 per person... taxes in, and including return. What a deal!!!
Because of these deals, we've seen a HUGE amount of New Zealand, which has been wonderful. It was even this deal that allowed me to take Dave to French Polynesia as his Christmas present. Thank you, Grab-a-Seat!
