 On 7 November 2006 an AirSea Lines Twin Otter seaplane landed at Royal Victoria Docks on the River Thames, London, at the end of a proving flight testing the feasibility of seaplane operations from the river.The company stated it was studying the possibility of domestic passenger flights from lakes, rivers and harbours across the United Kingdom, and envisaged up to 50 AirSea Lines seaplanes operating in the UK in time for the 2012 Summer Olympics in London.In 2007 AirSea Lines expanded its network into the Aegean from Attica, using the port of Lavrio (instead of the preferred location of Piraeus) citing insufficient infrastructure at Piraeus for seaplane operations.
