Delta Air Lines is adding a sixth nonstop flight each week between Atlanta and Brasilia, Brazil’s capital city, on May 31.

“Delta’s continued growth in Brazil has been quite significant, and this new flight will further support our strategy in this market,” says Nicolas Ferri, Delta’s vice president for Latin America and Caribbean. “The new frequency between Brasilia and Atlanta will offer more convenience to our customers who need better access to the country’s capital city and its surrounding areas.”

From May 31, Delta Air Lines’ schedule between Atlanta and Brasilia will see flight DL221 departing Hartsfield-Jackson Atlanta International Airport (ATL) at 9:20 p.m. on Sundays, Mondays, Tuesdays, Thursdays, Fridays and Saturdays and arrive at Brasilia International Airport – Presidente Juscelino Kubitschek (BSB) at 6:54 a.m. the following morning, local time.

In the other direction, flight DL222 is timed to leave BSB at 10:15 p.m. every day except Thursday, reaching ATL at 5:55 a.m. the following morning, local time.

Delta Air Lines is spending $1 billion on fleet-efficiency and customer-experience improvements from 2010 through mid-2013. The improvement programs include installing blended winglets on more than 170 Boeing 767-300ERs, 757-200s and 737-800s to extend aircraft range and improve fuel efficiency by up to 5 per cent

Delta Air Lines operates its Atlanta-Brasilia flights with Boeing 757-200s seating 162 passengers: 15 in First Class and 147 in Economy Class.

The carrier currently offers 32 weekly nonstop flights between the U.S. and Brazil, including service connecting Atlanta, Detroit and New York JFK to Sao Paulo as well as service linking Atlanta with Rio de Janeiro.

Earlier this year, Delta and Brazilian carrier GOL Linhas Aéreas Inteligentes began codesharing and started frequent-flier-program reciprocity. Delta flight numbers are now available on 56 GOL flights between Sao Paulo, Rio de Janeiro and Brasília and 15 Brazilian destinations: Belem, Belo Horizonte, Cuiaba, Curitiba, Florianopolis, Fortaleza, Goiania, Iguassu Falls, Joao Pessoa, Navegantes, Porto Alegre, Recife, Salvador, Teresina and Vitoria.

According to Delta, the two airlines expect the number of codeshare markets to increase to more than 30 by summer, pending government approvals.
