On Thursday, Dubai-based carrier Emirates confirmed that it had activated its codeshare with United.

Emirates passengers will be able to fly to three of the biggest business hubs in the US – Chicago, Houston or San Francisco.

Furthermore, Emirates customers heading to the US can access more than 150 US cities in the United network, via those three gateways.

Similarly, Emirates customers in the US flying to Dubai can connect onwards to several destinations across the Middle East, Africa, Central Asia and the Indian subcontinent.

Under the agreement, Emirates Skywards members can earn and redeem miles on all flights across United’s worldwide network. However, United’s MileagePlus members can earn miles on select flights in the Emirates network when travelling from Newark (EWR) to Dubai (DXB) on United Airlines and onwards to select destinations serviced by Emirates.

Emirates and United have an interline arrangement in place too that allows passengers to easily access several destinations in the Americas outside of the US. Emirates customers will therefore be able to choose from dozens more destinations in Canada, Mexico, the Caribbean, and Central and South America, via the three hubs of Chicago, Houston and San Francisco.

Emirates currently offers services between its hub in Dubai and 12 US cities, as well as five points across Canada, Mexico, Brazil and Argentina.

The five points that Emirates operates to in the Americas include Mexico City (MEX), Toronto (YYZ), Sao Paulo (GRU), Rio de Janeiro (GIG) and Buenos Aires (EZE).

Meanwhile, the airports that it operates to in the US are Boston Logan International Airport (BOS), New York’s John F. Kennedy International Airport (JFK), Los Angeles International Airport (LAX), Houston’s George Bush Intercontinental Airport (IAH), Chicago’s O’Hare International Airport (ORD), Washington D.C.’s Dulles International Airport (IAD), Seattle Tacoma Airport (SEA), Newark Liberty International Airport (EWR), Orlando International Airport (MCO), Dallas-Fort Worth Airport (DFW), San Francisco International Airport (SFO), Miami International Airport (MIA) and Orlando International Airport (MCO).

“We are extremely delighted to activate this historic partnership with United and significantly expand our footprint in the US. United’s vast network across the Americas will help us to offer more choice to our customer base from across the globe, and meet demand from across segments including the leisure, VFR, corporate travellers and students who can now connect seamlessly to and from a broader network of more than 150 domestic points,” said Adnan Kazim, chief commercial officer at Emirates.

Earlier this month, United Airlines launched a new nonstop daily service between its New York/Newark hub and Dubai International (DXB). United is thus the only US airline to offer nonstop flights between Dubai and the US. The new service marks United’s return to Dubai, which the airline previously served until 2016.
