So we will be flying into LAX on an overnight from NZ with Air NZ. I'm worried about the long wait at immigration with my 2 year old. On previous trip to Oz we've had him in a backpack but he'll be too big for that. My current thinking is to by a little cheapy umbrella stroller which, according to AirNZ website I can take on the plane so he can sit in that in the immigration queue. I'm not convinced they will actually let us go that though as I imagine if the plane is full they'll tell us it needs to go on hold ( this happened 5 years ago on a trip back from Oz with my older son). How have others handled a toddler at LAX?
