Since stepping down from the Olympic bid, Cassani has been working on plans for a new startup company, and appears as a business and management speaker on the public speaking circuit.
In 1997, facing increasing competition from low cost airlines Ryanair and EasyJet, British Airways decided to found its own budget offering, to be known as 'Go'.
[4] Later that year, the airline was bought by rival EasyJet (a move bitterly opposed by Cassani) and she was not offered a position in the merged company.
The organizing committee felt that her business background would give the bid a badly needed professionalism; the organizational reputation of British sport had already been tarnished when it won the right to host the 2005 World Athletics Championships but was forced to withdraw when the promised stadium could not be built.
During her tenure, the newly formed bid team grew to a staff of 80, with many large institutional backers, and gained increasing approval from a sceptical British public and political class.
Her team created the bid's master plan, which detailed where events would be held, what infrastructure would be built, and provided an overall budget projection for the Games.
In March 2004, The Daily Telegraph diary column printed claims that Cassani had been highly critical of Tony Blair, saying "To be frank he wasn't very bright ... the subject he got most animated about was beach volleyball."
On 24 September 2007, Cassani became the new chairman of the board at Vueling Airlines, replacing Jose Miguel Abad Silvestre, who resigned abruptly citing "managerial differences."
