Well, the situation in switserland is not completely what it is in Belgium when it comes to the intercontinental flights.
Swissair is not officially bankrupt (yet), they are using the government loan and are therefor still operaing some of their intercontinental flights (contrary to sabena/dat). The aim of all this is to slowly prepare crossair to take over all these flights now flown by swissair and then to file for bankruptcy.
In Belgium however, as Sabena is already bankrupt dat tries very hard to get on its own feed asap to take over the intercontinental flights from sabena. However, in the mean time no intercontinental flights are operated.
