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).
Customers flying on Blue fares can make changes to their itineraries, with the change fee varying based on the cost of the ticket. JetBlue will charge $70 for changes on fares of $99 or less; $90 for changes on fares of up to $149; and $135 on fares of $149 and up. Confirmed same-day changes will cost $50.
