Proposals to provide services were ranked by a seven-member voting panel, based on quality of vehicles, driver programs, operational plans, experience, fees, financial performance and references, Gann said.
Don Winder, attorney for Yellow Cab, said winning bids were decided by how much the companies were willing to pay for the privilege of doing business in the city, with a minimum annual payout to the airport of $225,000 for a 150-car fleet.
The city will be terminating its on-demand permits to Yellow Cab's 145 drivers and the 78 drivers with Ute Cab. City Cab, with 45 drivers, did not submit a bid.
"This is a pay-to-play system," Winder said. "The airport has decided to kill three Salt Lake City businesses that have been operating for decades, and throw hundreds of drivers out of work. Putting all these people on the unemployment list during this recession is incredible. Government should be promoting businesses, not killing them."
Gann said that the new companies will offer hiring opportunities to local drivers.
Ute Cab owner Ken Olsen said he's perplexed why the airport "would go outside the state to find providers when they have qualified companies right here. What about supporting local businesses? Seems that in Salt Lake City, it's just a slogan."
Yellow Cab has petitioned the Salt Lake City Council to reconsider the bidding process, and councilman J.T. Martin said he will examine data to see on what grounds the contracts were awarded.
Airport executive director Maureen Riley said the winning taxi companies "have strong reputations in the transportation industry and offer an exceptional approach to full service transportation, including the needs of customers with disabilities."
She added that federal law prohibits giving preferential treatment to local companies.
The companies also will have newer and more alternative-fueled vehicles. Each vehicle will be equipped with external and internal cameras, along with electronic maps and back-seat credit card payment systems, airport officials said.
To comply with the new airport mandates, however, cab companies will have to raise rates by 40 percent, according to the Salt Lake-based consulting firm Wasatch Economics.
Higher fares will turn away many consumers, said economic consultant Theodor Tatos, who conducted the study for Yellow Cab. Although it's often assumed that added costs can be passed along to business travelers without repercussions, convention planners consider many factors, including taxi fares, when selecting cities, according to Tatos.
The winning contractor, Ace Taxi Service operates more than 120 cars and vans in the Cleveland area to hotels, businesses and schools such as the Greater Cleveland Regional Transit Authority, Cleveland Public Schools and nursing homes.
The other winner, the Arizona-based Total Transit,operates 500 cabs and nonemergency medical vans in the Phoenix area and Tucson.
