Singapore Airlines (SIA) has planned to resume flights to Greek capital Athens on a temporary basis between June and October next year, targeting at the expected demand during the summer travel peak, the SIA said on Monday. The airlines said it took \"the difficult decision\" to suspend year-round services to Athens in October last year after \"a prolonged period of challenging operating conditions.\" The flights will be operated twice every week, on Mondays and Thursdays between June 9 and October 9, 2014. Boeing 777-200ERs will be used for the flights, the SIA added.
