The past week saw the Bureau of Transportation Services (BTS) revealing that average airfares in the US had declined in August as well after the sharp fall in July. Apart from the August reading on air fares, the past week saw updates from the likes of GOL Linhas Aereas Inteligentes and JetBlue Airways Corp. (JBLU Quick QuoteJBLU - Free Report) .

Of late, Latin American carrier GOL Linhas has been grappling with a number of headwinds including the weakness in Brazilian economy. The carrier continued its disappointing run with lackluster traffic numbers for August.

JetBlue, on the other hand, made it to the headlines with its environment-friendly initiative. The carrier inked a renewable fuel deal with SG Preston.

During the past week, and United Continental Holdings (UAL Quick QuoteUAL - Free Report) also came into focus with its expansion-related move. Additionally, the BTS disclosed June traffic data for U.S. carriers in the past week.

Recap of the Past Week’s Most Important Stories

1. GOL Linhas reported dismal August traffic numbers. Traffic – measured in revenue passenger kilometers – declined 5.6% from 3.1 billion recorded a year ago to 2.89 billion. Also, on a year-over-year basis, consolidated capacity (or available seat kilometers) was down 8.1% to 3.7 billion, mainly because of declines of 5.4% and 25.3% in domestic and international capacity, respectively.

2. In order to reduce carbon emissions, JetBlue Airways signed a deal with bio-energy company, SG Preston, to buy hydro-processed esters and fatty acids-based renewable jet fuel from the latter.

3. In a bid to further expand its operations, United Continental joined forces with DHL Global Forwarding to extend services in San Juan.
