Hello! I would like to address the lack of customer experience during the round-trip flight between NYC and Punta Cana. I had booked JetBlue to get my family with young children (5yo and 7yo) for a family vacation to Dominican Republic in the first week of November 2023. I plan all the trips ahead of time with reserved seats so there are no hick-ups during the travels. I had done the same this time and paid for the seats upfront and had my family seated together. Upon check in at the gate, after the boarding passes printed, I realized that my son, 5yo, has been seated somewhere else. I brought it to the JetBlue personnel immediately. The lady looked like she was working on something to resolve the issue. I waited patiently since I had paid for the seat and did not worry about it too much. It took her the whole boarding time, and my family were among the last few customers left to be boarded. She did not give me any solution. At this time, I had requested to speak with a supervisor or someone else, since I could not have my son to be seated somewhere else especially when the seat is paid for. She was communicating with someone who never came or appeared to be interested in this case. I got frustrated and told her that I would handle the issue myself once I got on board of the plane. No one seemed to help. I felt pretty disappointed with JetBlue, when they could not have their customer's back! On board I had asked a passenger to switch the seat with my son so he could seat with my wife. I had to give up my seat to him and myself be seated someplace else. Terrible! I did not have to do that! I had paid for the seat!!! Bad service. Anyway, JetBlue was not done yet - JetBlue made sure the return trip was even worse! The return Flight 1668 had seat misplacement as well. I was furious. However, I did not show my frustration to the staff since it was not their fault. On board, I had called stewardess for an assistance and requested if my daughter and I could be seated together since there was a mistake with our boarding passes. She checked the plane for seats and said no. I could not ask anybody this time to change the seats because one side of the three seats had a couple and the other side of the three seats had a child and a man. My daughter, 7yo, ended up seating with someone else in the aisle seat and I was in the aisle seat across her. I ended up holding her hand and she was very uncomfortable the whole 5hours. Very disgusted with JetBlue! I was waiting to get back to NY to address the issues with JetBlue. Apparently, the airline had charged me $50USD for changing a letter in my son's name and the check in attendant had made a mistake and switched my son's seats for both flights. When I contacted JetBlue, I did not want any discount for the terrible experience, I had simply asked the representative on the phone to give me the money I spent to pay for the reserved seats and $50USD charge for the name change. I was very straightforward with my request and did not wish to waste my time with JetBlue. After a brief hold, the representative came back stating that charges for the seats would be refunded but the $50USD would not. I thought to myself, JetBlue has failed terribly to protect its customer's satisfaction. JetBlue lacks not only customer experience but also the proper judgement on their management. Mind you, the call had been escalated to the management that could process a refund. Unfortunately, the management decided that the beyond screwed up family trip did not deserve a simple refund of a charge that should not be processed to begin with. I never requested any discount for the experience; I had requested to be refunded for the charges that JetBlue did not deliver but rather made it an obstacle course for my family. The idea is not about $50USD but the principle and accommodation, which JetBlue lacked. JetBlue must be ashamed. I am sorry that my family had to endure the flight. Thank you for reading. I hope it serves as a precaution to some families with young children. …
