Can do,
In the interim
Kiwi Flyer the insurances are no different from your existing Westpac card, though they are printed on nicer paper
Gotta Requalify I would be interested if you want to write a few lines about your experiences with the Westpac Altitude Platinum card, specifically the concierge (I take it that's also contracted to AXA) and customer service. Incidentally it's not a true Platinum Amex, because it's a credit card and a co-brand.
Furthermore technically the AmEx platinum charge card's issued down here in the pacific rim don't recieve access to those lounges anyhow. It's a long standing joke that one can buy 2 years of the AmEx International Dollar Card for the price of 1 in New Zealand, even though the IDC has more benefits - priority pass, hilton gold and automatic insurance regardless of how the tickets are purchased !
