Looks like the new changes to Electronic Tickets and emails now cause issues for Apple Mail users.
Has anybody had any luck in accessing the attachments in Apple Mail. In the Message Viewer I see that there are 9 items attached to the message however when I open the email there are only 6 (images used within the message)
I have visited a 'webmail' client from my ISP and can see that the three attachments are application/octet
eg-----=_Part_36423_948844686.1222065412539 
Content-Type: application/octet-stream;
name="E-Ticket booking ref MX5XXH.PDF"
Content-Transfer-Encoding: base64
Content-Disposition: attachment; filename="E-Ticket booking ref MX5XXH.PDF"

In the past year AIRNZ caused the same issue with the BoardingPass emails, but at least the invoice and eTicket PDF was accessible.
Interesting that when I spoke to AirNZ support last night I was advised that they could post or fax me the document, or they could try to email to a different address.  When I provided that address I was asked for one without an underscore as "we are having issues with underscores in email addresses, and also with Lotus Notes email too"
Concept of the appointment is great idea but fails in execution. (Only first leg, no timezone info and floating so is incorrect time when travelling, start time only not duration, Location would be useful)
