Etihad Airways has announced a new code-share alliance with Turkish Airlines. The alliance will allow Etihad customers to choose from daily services between Abu Dhabi and Istanbul, instead of the four flights a week the Abu Dhabi carrier currently serves with its own aircraft between the two cities that began on June 1. Etihad said it would place its two-letter 'EY' code on Turkish Airline's flights from Istanbul to Abu Dhabi.
