Instead of the usual https://flightbookings.airnewzealand.co.nz/isbook_en_NZ/book/searchForFlights.do
And then realised that Air New Zealand accepts both GET and POST variables in their searchForFlights.do page. Until this I never really thought about the data you pass on to the Air New Zealand search engine.
I fired up Tamper Data, which is a Firefox plugin, and lets you view information submitted via GETs and POSTs, and to the right is a screenshot of the POST variables. Fairly straight forward. Do note that if you try and access this page randomly you’ll probably get a CAPTCHA page you’ll have to solve. But anyways, a cool method to bookmark a search to a particular destination.
