The airline sector is experiencing a significant lift in pre-market trading, with the JETS ETF up 2.30%. This move is primarily attributed to a notable decrease in crude oil prices, a major operational expense for carriers. Both WTI and Brent crude futures have fallen over 2% this morning. This drop in oil prices eases concerns about fuel costs, which have been a significant headwind for airline profitability. The positive sentiment is also supported by a broader uptick in U.S. stock futures.
