JetBlue has a policy that can provide you with a refund or credit if the price of your flight drops after you've purchased your ticket, but it depends on the circumstances. The airline offers a Best Fare Guarantee, which allows passengers to request a refund if the price of the same flight drops after booking, as long as the fare difference is significant. This typically applies when the price drops shortly after booking and before your flight’s departure. However, there are a few important points to consider.

First, this refund option only applies to flights booked directly through JetBlue’s website or customer service. If you booked through a third-party site or travel agent, you would need to contact them to inquire about any refund or price drop policies they might have. To request a refund due to a price drop, you will need to contact JetBlue directly within a reasonable time frame, usually within 24 hours of booking. JetBlue may refund the difference in fare in the form of a travel credit or voucher, which you can use for future flights.

In some cases, JetBlue may allow you to cancel your existing booking and rebook at the lower price if you contact them promptly after noticing the price drop. This option might require you to pay a change fee, depending on the type of fare you purchased, and the refund policy can vary based on whether you booked a refundable or non-refundable ticket. For non-refundable tickets, the airline may not offer a direct refund but could allow you to apply the difference as a travel credit.

However, it’s important to note that JetBlue's policy doesn’t apply to all price drops. It primarily focuses on price reductions for the same fare class and route. If a fare drop is part of a special promotion, or if you’re switching to a different class of service or a different date, it may not be eligible for a refund.

JetBlue’s "Price Drop Protection" program, which offers a refund or credit if the price of your flight drops after booking, can be beneficial for travelers who book well in advance. This program can help you feel more confident that you won’t miss out on a lower fare if the price decreases later. It’s worth keeping in mind that this program doesn’t apply to all fare types, and certain discounts or sales may not be covered.

If the price drop occurs closer to your departure date or if the flight you initially booked has significant schedule changes, JetBlue may provide more flexibility for rebooking or applying the difference as a credit. Additionally, if your flight is eligible for a refund due to a price drop, you may be subject to certain terms and conditions, such as booking a similar route or flight within a specified time frame.

In summary, JetBlue may offer a refund or credit if the price of your flight drops, but this depends on the type of fare, timing, and specific circumstances. It’s best to contact JetBlue as soon as you notice a price drop to understand your options and ensure you meet any deadlines for refund requests.
