Passengers can now access free Wi-Fi at the world's busiest airport.

Atlanta's Hartsfield-Jackson International Airport has dropped its $5 fee to access Wi-Fi in its terminals.

"Now, Atlanta Mayor Kasim Reed and airport officials plan to celebrate the long-awaited arrival of the amenity at the airport Wednesday," reports Kelly Yamanouchi of The Atlanta Journal-Constitution.

Hartsfield-Jackson officials have announced a press conference for 9:30 a.m. ET on Wednesday.

Interm airport manager Miguel Southwell tells Yamanouchi officials believe dropping the Wi-Fi charge will alleviate a "competitive disadvantage" for Hartsfield-Jackson.

In the meantime, the Atlanta airport is touting its free Wi-Fi on its website.

As part of the initiative, Hartsfield-Jackson has just completed an upgrade of its Wi-Fi infrastructure that allow more users to simultaneously access the system, the Journal-Constitution reports. The older system topped out at about 2,000 users, but officials expect 15,000 users at any given time once the free Wi-Fi kicks in.

Atlanta's Hartsfield-Jackson International has been the world's busiest airport many years running. In 2013, the airport handled about 94 million total passengers, according to Airports Council International. Beijing was second on the full-year list for 2013 with about 84 million passengers.
