<h1>Air Services Agreement enables codeshare operations expanding long haul capacity, connectivity, and trade related economic effects.</h1> The IndiGo-Turkish Airlines arrangement functions under the bilateral Air Services Agreement, which allocates reciprocal weekly flight entitlements, and combines leased aircraft operations with a codeshare partnership. Codesharing permits issuance of a single ticket for travel on a partner carrier and extends IndiGo's access to over forty long haul destinations in Europe and the United States. The arrangement increases long haul capacity, improves seat availability and affordability, enhances connectivity from Indian hubs and smaller cities via two stop itineraries, and is represented as supporting trade, employment and additional revenue.
