I just looked at my reservations with Orbitz again and it says "Seats are unassigned on one or more of your flights. The airline will assign your seats at check-in." When I booked it had me go through all the seat assignments. I've never booked a flight through Orbitz before but I've always been able to assign my seats.
I thought maybe Air New Zealand doesn't assign seats for their domestic flights so I tried to assign seats again and none of my seat assignments are there. When I submit after making new seat assignments, I keep getting a error that says please try again. Please tell me I should be able to get my seats assigned in advance, at least for my main flights. I really don't want to sit by myself on a 13 hr flight! I'm flying United and New Zealand Air over and New Zealand and Delta back.
