Winnipeg's Richardson International Airport has broken its record for passenger traffic for the second year in a row.

The airport saw 3,778,035 passengers in 2015, which is three per cent more than 2014, airport officials said Wednesday. 

"Momentum is building in the Winnipeg market, as evidenced by the solid growth in our passenger numbers for the second consecutive year," said Barry Rempel, president and CEO of Winnipeg Airports Authority, in a news release. 

"We are encouraged to see a growing number of people flying to and from Winnipeg. It is particularly helpful in our efforts with air carriers to increase capacity on existing routes and in attracting new destinations to better serve our community," he said.

Although seat sales are down on some routes, major carriers made changes to routes to meet demand, airport authority officials said. New seasonal flights to Ixtapa-Zihuatanejo, Mexico, were added last year.
