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).
The airline that charges the most for the first checked bag is Spirit Airlines with a $45 fee, the second checked bag costs $55, and you will be charged $100 for an additional bag. American Airlines charges $25 for the first checked bag, $35 for the second, and $150 for an additional checked bag. JetBlue charges $20 per one-way ticket for the first checked bag, when you pay at a kiosk or via web check-in. You will pay a higher fee of $25 when you check your fist bag at the check-in counter.
