Very old aircraft overdue for repacelement. Carpets worn. Seats broken. Quite dirty. We arrived in Stavanger early and docked at an domestic terminal with onward bus journey to international arrivals and passport control. I booked airport assistance because I am disabled. the wheelchair didn?t turn up on time. The bus left without me. I was left sitting on the tarmac in the wind and rain while radio traffic was needed to find a solution. Eventually the assistant was told to push me through to international arrivals because bus was busy elsewhere.
