Hi I'm having the same problem. I'm searching ANZ flights from LAX to AKL this summer on C (biz class). EF says there are (I) seats available, ANA says none. June 1st departure is what I am talking about

ANA says:
6/1
(TU) NZ001
Los Angeles Auckland
21:30 05:25
+2 744 Full Full Full

and EF says:
NZ () 1 0 LAX
06/01/10
9:30 PM AKL
06/03/10
5:25 AM 744
Business - Awards using Airpoints & Complimentary upgrades for Golds I 2


Any reason why they don't match? when I mess with the dates on ANA with the arrows, and come back to my original date all of a sudden everything says "RQ"

I am confused
