Kirk H.
Very disappointed by the fact that I had booked the wrong venue to collect The bus and could not change the ticket to The Hard in Portsmouth. So had to buy a new ticket.
Julia K.
Service was over an hour late to Heathrow If SAS hadn't upgraded me to business class I would have missed my flight. As it was, I couldn't check in my bag, and lost various items (Marmite/creams etc.) that weren't allowed in handbaggage - and had a mad dash all the way to the gate, to arrive as they were just closing the flight...
