But there are at least two people from Greece with ties to New York who are still missing.
Siblings Sascha and Alexander Pinczowski were in the Brussels airport Tuesday at the time of the attack.
"Brilliant young man, clever, intimidatingly smart," said Jim Cain, future father-in-law of missing man.
Cain spoke fondly of the young man engaged to his daughter Cameron, 29-year old Alexander.
Alex, as he's called was at a ticket counter inside the airport in Brussels when Tuesday's terrorist attacks took place.
Alex, and his younger sister Sascha were about to depart back for New York City, and were on the phone with their mother Mariaan in the Netherlands when the unthinkable happened.
"Mariaan said the phone sounded like it went under water, so that's the last contact anyone had with Alex or Sascha," Cain said.
"So there could have been an explosion right there, obviously," Eyewitness News asked.
"I think that's the presumption," Cain said.
His daughter is pleading for information on Twitter, but so far has heard nothing.
Wednesday night, the Cain family travels from New York to Brussels, trying not to lose hope.
"But it's been more than 24 hours now. And so, we know that there's a possibility, the news, when it comes, may not be good," Cain said.
Both Alex and Sascha planned to settle here in New York City. Sascha, graduated from Marymount Manhattan College on the Upper East Side last May with a degree in Business. She was looking to move back from Europe, and as fate would have it figured she'd join her brother on his trip.
"Sascha apparently said, 'by Golly, if Alex is going to New York, I'm coming, too,'" Cain said.
She recently interned at Shiraz Events in Manhattan.
The company Wednesday told Eyewitness News "Sascha is a bright, hardworking young woman with great energy and a joy to have around and that she has a great career and life ahead of her."
And in another sad twist, it just so happens that Cain is a former U.S. Ambassador to Denmark who dealt with more than his fair share of terror threats a decade ago, during the crisis over a cartoon of the prophet Muhammed.
"You live through those scenarios, you think about those, but you can never imagine that something like this would happen to your own daughter, your own family, and it's horrible beyond imagination," Cain said.
Most of Alexander and Sascha's family is in Greece and the Netherlands.
