Been thro 3 times in last 6 months. Twice arriving once departing. 1/ Suitcases take ages to collect. 2/ persons meeting passengers confused re which terminal to wait at. They couldn't find info, talking to other people they had the same problem. 3/ signage to short-stay carpark poor. Drove round loop 3 times when catching flight without success so they had to leave me at drop off Zone, resulting in upset parents as I live in Australia and they don't see me often. Plan was to have coffee n say goodbyes. Overall it's the most unwelcoming international airport I've been through and if it wasn't for the excellent Qatar scheduled flights I wouldn't use it.
