Just got an email from Air NZ advertising a special to Honolulu. Nothing wrong with the special per se (approx NZD 620 WLG to Honolulu one way) but:

'For airfare only bookings paid with credit, debit or charge card, a fee of $17.50 per person per one way journey applies. For airfare only bookings made through our Contact Centre or Air NZ Holidays Stores a non-refundable service fee of $60 per person, per one way journey applies.'

Seems almost like Ryan Air in its attempt to get extra revenue on the sly.
