The airline sector is trading higher, with investors focusing on the benefit of declining crude oil prices, a major operational expense. This positive sentiment is outweighing the recent disruptions caused by a significant FAA telecom outage in the U.S. Northeast. While the outage caused numerous delays and cancellations, its resolution has removed a point of uncertainty for the market. The upward momentum is also supported by recent bullish commentary from major carriers like American Airlines regarding strong travel demand and revenue growth.
