Further to Michael Walton's letter "US double standards" (Flight International, 19-25 February), another example of questionable practice must be the coincidental number of contracts supported by GE Finance, which include US and Airbus aircraft also fitted with GE engines.

It might be argued that this practice makes good business sense as GE Finance certainly seems to flourish. But it cannot be good business practice if strings, in terms of choice, are part and parcel of the operating procedure.

I thought the Microsoft issue put this sort of practice under the microscope - apparently not.
