I use the UA PNR but is unable to pull it up at Viewtrip.com.

Would want to see it because the travel is mainly on Air NZ and numerous changes have happened since the ticket is issued last June. 3 re-issuance of tickets have since occurred. The latest ticket, in the Fare details, all my I class on Air NZ now changed to X class on the e-mail I got. It really bothers me.
