PER - ADL

Overall experience was satisfactory. Could have been easier to access airbridge on departing Perth as Gate 55 did not accommodate a wheel chair meaning a fair bit of pushing and restraining through a nearby Gate also using lifts. Adelaide -we had assistance on arrival with the wheel chair until a level floor was reached.
