The flight attendants have become sales associates too. They push affinity credit cards for the particular airline, headphones, food, drinks, movies, and I guess blankets and pillows cost extra on some airlines too. To make it easier they seem to be moving to a cashless society in the air. Hand over your credit card and for maybe $25 you can get a pillow, a soda, a sandwich, a movie, and headphones to listen to the movie. And while you are relaxing, why not complete this application for the Delta Skymiles AMEX Card? We'll give you 25,000 bonus miles if you apply while airborne!
