Never come through on advertised price
Attempted to book Glasgow-Sydney in April 2012 via advertised price sites (cheapflights etc) and called many agents but they all appear as the same agent - travelup. Advertised for around 732.20 for same price for weeks, however flight is quoted at a lot more when call as advertised. It appears as though the same company advertise under different agents name and trade from outside Europe. It's a poor name they give good reputable agents whom advertise and supply the same price. BE CAREFULL with these agents and do your homework!
