JW411,
Did Freddy really expect that airlines which had developed lucrative routes would stand by an let him cherry pick their business? That ain't how it works in the big world.
As you know very well Laker, by trying to play the FX market, were, in part, architects of their own downfall.
Laker and Virgin are both innovative and competitive companies which have their place in British aviation history but Virgin suceeded as much by debt control and financial structure as by willingness to sue and, in any case, had Laker survived there would probably have been no place for Virgin.
