The question now being discussed in the prisons is whether the detained campaigners will accept being deported quietly or will they refuse to co-operate with Israel?
The foreign airlines operating in Israel told Israeli newspaper Haaretz they they will have a hard time flying large groups of pro-Palestinian activists who were refused entry into the country back to their destinations of origin.
A senior official for one of the large European carriers told Haaretz on Saturday that "The airlines will have a hard time dealing all at once with large groups of pro-Palestinian activists that Israel wants to deport.
"We're talking about the peak of summer traveling season and the flights are full. We'll have to act accordingly and make different preparations, but first of all, we'll have to receive instructions from the head of the aviation authority in Israel for the deportation of the activists," he said.
"At present, we are unprepared to deal with this, in terms of human resources and in terms of amount of planes," the official added.
The airline official estimated that the massive deportation will begin on Sunday, continuing into the week, and will occur in small groups.
