In today's video, Brendan discusses the airline industry and its recent performance. While several airline stocks have been performing well this year, with some even hitting 52-week highs, Delta recently announced subpar May revenue numbers. The company increased revenue per available seat mile by 6%, lower than the 7% that it had projected. This is mainly due to Southwest offering discounts on last-minute fares from Atlanta. In the video below, Brendan discusses what this means for the industry, and also examines the European Union carbon levy program and Delta's recent refinery purchase.

Ultimately, Brendan thinks that long-term investors should avoid most stocks in the volatile airline sector. But that doesn't mean there aren't opportunities elsewhere.
