neb: I don't think so, it says "checked in at Auckland Airport 45 minutes prior to their scheduled departure" and "Casey took the children through security while her husband went to check in his daughter's wheelchair". So I'm reading it to say they checked in ten minutes before checkin closed, she took the children through security and he want to check in the wheelchair, which could even mean that he had a lot less than ten minutes to spare to check in the wheelchair if they were already at T-10 for their standard luggage. Having said that, the article isn't at the level of court testimony so the description of the timeline could be stated misleadingly or incorrectly.
I'm thinking that maybe they were flying with no checked luggage (apart from the wheelchair). So checking in for the people was at a kiosk or even done online before going to the airport, hence over quickly and they could head off to security because they knew time was tight whilst hubby dealt with the wheelchair.
