My flight into Seattle from Salt Lake City late Thu night was fine and without incident (the way all travelers like it). It’s just two hours. Friday’s Wall Street Journal had an interesting write-up about Delta’s fleet. It is very large, but older than most airline fleets, and made up of many different types of aircraft – 10 different models and some 750 planes altogether. The airline has been profitable for the third year running last year, but spent $12 billion on jet fuel : its biggest expense. So recently it made a bold move. In September it plonked down $150 million for an idled Conoco refinery, as a way to manage high jet fuel costs.
