WAW - JFK

The only thing that I could say I really liked was the speed of travel. I think the flight time was significantly reduced, but I only think happened because there were delays in our departure time. We wound up arriving about 1 hour later than originally planned. A few things that could have improved was the entertainment available on board and also the ability to view the flight details in real time. I was just the lucky passenger to get a busted screen so I couldn't watch any entertainment. The passenger sitting next to me was kind enough to switch seats with me once his move was done. The choices for movies and shows were ok, nothing great, but I was grateful some ok movies were available to pass the time. I was not very happy with the absence of flight details. There was a timer that showed how much time was left in the flight, but no other details. Other airlines I've been with offered interactive maps that showed you where the plane was traveling like a normal GPS app would do on your phone which is super nice to have. Flight attendants were nice and helpful. The clarity of the announcements was terrible. Even in English, I could hardly make out what the person was saying. Please make improvements.
