The 'companion fare' offer is offered to Business Class passengers travelling from Nairobi to any point on Emirates' network of above 100 destinations; and to First Class customers travelling straight to Dubai.
Both passengers must travel together for the whole journey and be confirmed on the similar booking.
Essa Sulaiman Ahmad, Emirates Regional Manager for East Africa said: "At Emirates, we are always on the lookout for chances to reward our loyal customers and these particular companion fares actually do represent incredible value for money."
"Whether customers are travelling on business or for leisure, this offer will allow them to experience Emirates' world-renowned premium cabins for less," said Ahmad.
"What's more, they will still obtain all the extras that build our First and Business class such an outstanding proposition, as well as our chauffeur-drive service to the airport; devoted priority check-in, extra baggage allowance and access to our executive airport lounges. Their Skywards account will also be credited with the full amount of miles," he added.
Emirates is one of the biggest international air carriers within Kenya, operating 14 flights each week from Nairobi to Dubai.
