I recently traveled with Israir Athens and found out what terminal is Israir at Athens. It was easy for me to find my way because there were signs clearly indicating the terminal. It was also handled quite well. The self-service kiosks and the welcoming counter with their courteous staff made checking in quick and simple. Wait times were kept to a minimum by the efficient and well-coordinated security protocols. There were plenty of restaurants and shops inside Terminal B to pass the time while waiting in line.
