Bad business practices. They screwed up the reservation, were AWARE that the reservation was set for the wrong day, and not only refused to make accommodations, date changes, or refunds, but even refused to admit that they were at fault. And, after reading reviews from people who have stayed there, I feel like I dodged a bullet.
As of June 1 2015, JetBlue has began charging for all checked bags, including the first checked bag, on its lowest priced fares. All checked bags must not exceed 62 (157.48 cm) in overall dimensions (length + width + height) and cannot exceed 50 pounds (22.73 kg).
JetBlue Airways (airline) Because JetBlue does not overbook their flights like many carriers, a cancelled flight increases the potential that the seat be left unsold at time of flight. JetBlue will generally require a change/cancel fee of $100 to offset the potential losses incurred. JetBlue does offer refundable fares for customers that require flexibility in their schedule and will also look at individual customer concerns on a case by case basis.
