JetBlue and American Express often team up to offer good discounts and here's a nice one: you can get $10 off any transcontinental one-way fare ($20 off round-trips) for fares charged to any Amex Card with this special offer.
Just purchase a transcontinental flight before June 30 and fly before June 30 except Friday or Sunday. Don't have an Amex Card? Well, maybe it's time. Amex is the "official" card of Airfarewatchdog.com because we love how fast they replace a card when it's lost or stolen (or simply misplaced, as happened to me in San Jose, CA recently). They'll have a new card in your hands in 24 hours. Visa and Mastercard take a lot longer. Plus, their cards for business have superior online management tools so you can slice and dice your expense reporting in many different ways.
