SQ operated fifth freedom sectors intra-Europe for decades because until recently there weren't economical medium-sized long haul aircraft capable of working nonstop point-to-point flights. Today only ZRH
As Swissgabe has mentioned, SQ
has never really pushed those flights, and unlike what some people on this forum seem to believe, those fifth freedoms are hardly lucrative. With only a handful of frequencies, SQ
