It sound's like JetBlue really got caught off guard with this storm. If I were you, I would send JetBlue's customer care department an e-mail. Believe it or not, they actually do read and respond to their e-mails. Since your flight was canceled, you are entitled to a full refund. Because of the poor communication on JetBlue's part, they may also throw in a future flight voucher for your inconvience. I am a former B6 employee. When I worked there, they would post letters like yours on the employee website to remind us that in extreme situations (hurricanes, snow storms, etc.) we need to be more compassionate towards the customers.
