JetBlue has partnered with ISIC to offer full-time students an 11% discount on all of their flights.
ISIS is a non-profit organization that issues student identity cards worldwide. Individuals must purchase an ISIC identity card to be eligible for the discount. The annual cost of the card is $22. ISIC's website lists the following eligibility requirements:
Full-time students age 12 & over currently enrolled for the academic year 2008-2009 at an accredited institution and matriculating towards a diploma or a degree. (Continuing education and language school students are not eligible).
You will need either a photocopy of school ID showing validity for 2008-2009 or a photocopy of your transcript/report card/tuition bill receipt for 2008-2009 academic year.
This can be a great deal for students and for parents traveling with kids who meet the eligibility requirements. The $22 ISIC membership can easily pay for itself in one or two trips on JetBlue. Additionally, the card offers other discounts such as 15% off on Amtrak, 10% on Target.com purchases and many others. See ISIC's website for additional information.
