Uber and Lyft are pushing back against proposed changes for rideshare companies at Boston's Logan International Airport. Massport officials are proposing higher fees and new dropoff and pickup locations for rideshare services to help reduce the number of empty vehicles heading to and from the airport. All Uber and Lyft pickup and dropoff locations would be moved to the central parking garage instead of dropping off passengers at the terminal or picking them up at designated pickup locations close to each terminal. Officials hope this will allow vehicles to drop off passengers, and pick up new ones, eliminating so-called deadhead trips, where rideshare vehicles arrive at or depart from the airport empty. Officials said rideshare services made 12 million trips into and out of Logan Airport in 2018 and moved only seven million passengers. According to officials, the change could reduce passengerless rideshare vehicles by as much as 30 percent. Spokespeople from both Uber and Lyft said Logan would be the only airport in the country where curbside dropoffs and pickups would not be allowed.In addition, the $3.25 fee passengers pay when they get picked up at the airport by Uber or Lyft would increase to $5 under the Massport proposal. There would also be an additional $5 fee for those who are dropped off.The fees would drop to $2.50 for those sharing a ride.An Uber spokesperson said the company is willing to pay a higher fee, but not as much as Massport is asking for. The spokesperson said Uber also proposed a tech fix called Rematch, where passengers would be dropped off at one terminal and others would be picked up at another terminal, with a fare, as the rideshare exits the airport.Uber said it has been asking Massport to try a Rematch trial for two years, but has never been given the chance to try it. "We laid out a proposal to the airport that can reduce congestion, raise new revenues and be implemented quickly with little upfront cost to the airport -- all without forcing customers to be picked up and dropped off in a distant parking lot," said the Uber spokesperson. "Our hope is that we can work with Massport on a solution that works for the airport as well as drivers and riders."A Massport spokesperson disputed that claim and said Rematch was tested a few months ago, with an Uber representative in the car. According to the Massport spokesperson, the test determined Rematch would add to congestion.A Lyft spokesperson said the company's biggest issue with the proposal is that other modes of ground transportation, such as personal vehicles, taxis and limos, would not be affected by the changes. Lyft believes all modes of ground transportation should be subjected to the new proposed fee structure."We know how important it is that riders can affordably and conveniently get to Logan Airport," said the Lyft spokesperson. "We're in discussions with Massport about better ways forward that avoid many of the negative consequences of Massport's approach." At a Massport board meeting on March 21, agency officials said the use of ride-hailing apps to come and go from the airport is exploding.Officials said the moves would clear space from crowded terminals because rideshare vehicles account for about 40 percent of curbside traffic during peak hours. Massport officials said their data indicate a good portion of the riders using Uber and Lyft are deserting public transportation, including the port authority’s own Logan Express buses.Massport said the initiatives are expected to eliminate up to 3 million vehicle trips off the roads and double Logan Express ridership while improving the customer experience and reducing emissions. "The bottom line is we need more people to get to and from the airport in fewer vehicles, and we think we can do that with these new strategies," Massport acting CEO John Pranckevicius said. "This plan is better for our customers, better for the community and better for the environment."The Massport board is expected to vote on a new rideshare fee structure on April 25. A Massport spokesperson said the proposals will be on the agenda but it is not clear when a final decision will be made. No public hearings regarding the proposals have been planned, according to the spokesperson.
