Jetstar forces wheelchair passenger to crawl across tarmac

[Angle of Attack]

There seems to be some confusion about policy here. Jetstar required the pax to check in their Wheelchair at check in, while apparently their policy is pax can take wheelchairs to the boarding gate similar to QF and that includes domestic let you remain in your own chair all the way to the aircraft door then you make your way to the seat via aisle chair or assistance depending on the passengers mobility. I am pretty sure Virgin also do this. Ground staff put the chair in the hold then their own chair is there waiting for them at the aircraft door at destination. I don't think anyone is suggesting a passenger enters the aircraft in their own chair, no one does that besides it wouldn't fit!
Seems the groundstaff on this occasion improperly required him to check in the chair while policy is they can remain with it until boarding.
