Aegean Airlines handled 7.9 million passengers in 2014's first nine months, representing a 14% year-on-year increase.
Domestic numbers rose 16% during the period, says the Greek carrier, while the international figure increased 12%.
Cash and short-term investments stood at €264 million ($328 million) on 30 September, showing improvement despite a share capital return in July plus pre-delivery payments to Airbus.
"We have managed to deliver improved commercial and financial results, driven by synergies from Olympic Air integration, network optimisation targeting improved connectivity, as well as higher tourist flows," says managing director Dimitris Gerogiannis.
"Our expansion strategy has yielded positive results in a period of intensifying competition and despite traffic weakness demonstrated from the Russian market."
Aegean plans to take delivery of seven new Airbus A320s over the coming two years.
