Booked this trip on JetBlue. First leg is flight #737. 36 minutes to change planes. Second leg is flight #1721. Checking flight aware it seems that flight #737 is late often AND flight #1721 often leaves early. I don’t understand why JetBlue sold me a ticket that appears to have a high chance of failure. I haven’t flown in 20 years. I hate flying. So stressful. Thanks to anyone that can explain this....
