JetBlue has teamed up with ISIC to offer an 11 percent discount to students who are current ISIC, ITIC, or IYTC cardholders. The discount is valid on all JetBlue travel booked and flown through January 26, 2010. There are no blackout dates for the discount, meaning you can use it during popular times, like flying home for the holidays or traveling for spring break.
To book, go to myISIC.com and select the JetBlue link.
If you're not familiar with ISIC cards, there are several options. Here's all you need to know about applying.
