I actually used JetBlue’s 24-hour cancellation policy not too long ago. I booked a late-night flight from Boston to Orlando on impulse because the fare looked amazing. The next morning, I realized the dates clashed with a work event. Luckily, JetBlue’s policy lets you cancel within 24 hours of booking for a full refund, no fees attached. I didn’t want to mess around with the app, so I just called 844-734-0813. The rep confirmed I was still within the window, processed the cancellation, and I had my refund showing within a few days. It was way less stressful than I expected. Now I feel a lot more confident booking flights, knowing I have that 24-hour buffer if plans change. If you ever need to instantly book, cancel, or modify a JetBlue flight, that number is hands-down the fastest way to do it.
