Frank Talk: Berkshire’s Delta bet shows why quality matters in airline stocks

Berkshire Hathaway has invested $5.4 billion in Delta Air Lines, despite Warren Buffett's past skepticism about airlines. The stake, now 1% of Berkshire's portfolio, was acquired during a period of high fuel costs. Analysts suggest Delta's refinery and strong financials make it a quality pick in the sector. Delta's earnings report, set for October 9, will be closely watched for revenue guidance and pricing power.
