The single five-year deal from April will replace the current at Scotland’s busiest airport, which include a City Cabs-Central Taxis black cabs consortium and private hire firm Onward Travel.
The airport, which handles 9 million passengers a year, said the new contract would also ensure minimum vehicle quality.
It said there were no current service standards such as maximum waiting times.
A spokesman said: “The new contract will make sure there are always cars available. Some passengers have had to wait for a taxi at night.”
