Newer planes being acquired at least have a small tray for working or reading or to set down a drink. Most seats do not recline, and space is tight. If you are over 6' tall consider paying extra for a seat with extra legroom.

On June 18th, I flew from RDU to JFK, NY. The plane was delayed in the runway for 1+ hours. As soon as I got out of the plane, I got a wheelchair (dur to my heart and back pain) and told the agent to go as fast as he can to Turkish airline terminal so we can catch the flight. We arrived at Turkish airline gate and the airplane doors were closed. I asked and almost begged to let us get in, but our request was denied. Therefore, we lost our connecting flight by Turkish airline to Istanbul, Turkey. We still had 20 minutes left from the departure. But Turkish airline said, they close the door 40 minutes before the departure. Around 12:15 AM (now is June 19th), I walked all the way from Turkish airline to JetBlue ticket counter (half an hour walk) and asked for next flight to Istanbul. After waiting for 2+ hours in the line, JetBlue indicated that next day flight to Istanbul is all sold-out and Turkish airline does not have any space from JFK to Istanbul. The agent said, why don’t you get a hotel and come back tomorrow morning and there might be a space for you. She said, most of time, there is a cancellation, and they should be able to accommodate us. Then, we have started to search for near-by hotel and after 2+ hours searching (all near-by hotels were sold-out) around 3:30 AM we found a Comfort-Inn which was 10 miles away. We got Uber and went to that hotel. The guy asked for $230+$50 deposit cash (no credit card) per person for only 6 hours as we had to be out by 12 PM. My son and I got 2 rooms very close to lobby (Room# C15 and C17). Once I got to my room, I saw flies and bugs in the corner of my room. At this time, I thought about getting a rest and try to connect my next flight to Istanbul which was extremely important to me. Once I got into the bed, it was extremely uncomfortable. The bed was uneven and bad. To make the long story short, I only slept one hour (at the most) due to around 6 AM, lots of kids in the lobby were making noise which I could hear them well. They only reimbursed one of the rooms and the other one they charged us as my son had the same problem as me. I did not argue as my goal was to get to JFK airport and get my ticket to Istanbul to see my nephew and his new wife. We came back to JFK airport and again stayed in the line for 2+ hours. Once it was our turn, the JetBlue ticket counter indicated; they don’t have anything from JFK to Istanbul. However, they have a flight from JFK to Boston and from Boston to Istanbul. I said, Let’s get that ticket, immediately The JetBlue agent said, I had to go to Turkish airline “Lost and Found” section to pick up my luggage and hand carry it back to JetBlue from JFK to Boston, then from Boston to Istanbul. This means, I had to go back again all the way to Turkish airline in another Terminal, get my luggage and bring it back to JetBlue. Due to so many people missed their flights, I had to wait for 2+ hours to get my luggage due to “Lost and Found” being so busy with so many lost luggage from other passengers. After 2+ hours, I picked up my luggage and took it all the way back to JetBlue (half an hour walk). I got to JetBlue ticket counter and re-checked my luggage going from JFK to Boston and Boston to Istanbul. I spent 3+ hours walking around and then I went to JetBlue’s gate for departure to Boston at 7:30 PM and then from there depart to Istanbul at 11:30 PM. Around 7:10 PM, the agent announced that, the plane which was supposed to pick us up has not arrived and there will be a delay. I asked the ticket counter agent, how long is the delay and he said, he does not know. Around 8:30 PM, the plane was arrived. The agent told me, by time they board us, it will be 9:00 PM and the soonest we get to Boston, it will be between 10:30 to 10:40 PM which Turkish airline closes the gate for their 11:30 PM departure to Istanbul. So, the agent said, there is no way we could make on-time and I will miss the flight from Boston to Istanbul. I went back to the ticket counter, and they said, they don’t have anything next day (Tuesday June 21st) and asked to stay in the hotel for another night. At this time, I was unbelievably shocked and stunned by JetBlue and how they treated me. Being in JFK airport and that bad hotel for over 30+ hours, not having my medications with me, I was at a point of falling due to being weak of not taking my medicines. I never thought this would happen to me. I decided to go back home to RDU, NC as we have missed my nephew’s wedding on June 19th and also missed the “Ceremony after the Wedding” on June 20th. There was no point for us to go to Istanbul as my nephew and his wife were gone to Honeymoon and all relatives were going back to their countries. We were extremely disappointed as it happened twice and the level of caring we received were extremely low. JetBlue agents did not even care that we lost connecting flights twice. They were all laughing, working very slow, talking personal and eating Pizzas while taking care of JetBlue tense customers. At this point, we decided to go back home to RDU, NC. This was due to being weak and having dizziness. The agent said, they will issue us 2 on way tickets which will be paid for. The plane was supposed to leave JFK towards RDU at 9:55 PM. Guess what, it left the airport at 11:30 PM, and arrives in RDU around 12:45 AM. As soon as I got home, I took my medications, passed out and slept for 11 hours. On Monday I rest all day as my heart and my body were aching. Yesterday, I was in contact with jet Blue (Code share department) as well as Kayak agency and other agencies for hotels and tours which all were cancelled due to JetBlue delays which occurred twice back-to-back on Saturday and Sunday. In summary, I lost my nephew’s wedding who is like a son to me. While I was in airport, we spoke on the phone, after the Wedding and after the ceremony. He said, uncle, without you, this wedding was meaningless to me and my bright. As soon as he said, I cried. It broke my heart and we both cried over the phone. These back-to-back delays happened only because of JetBlue. My nephew and I lost a big one here as I am still at lost and could NOT believe, this happened to me.
