One of the airport’s major successes last year was its $350 million, nine-gate expansion, which included six new international gates and more than 30 new and remodeled concessions.

The full cost of the airport’s next planned expansion—to be completed in 2040—has yet to be released. However, airport spokesman Bryce Dubee said the airport is self-sustaining and does not use taxpayer dollars for its projects.

Funding instead comes from grants, bonds and up to $4.50 that can be added to each passenger’s plane ticket for “facility charges,” he said.
