we were told the night before that the flight would be delayed ~50 minutes but that we should show up on time. We did but at the new doors open time people were still deplaning from our aircraft. We finally left the gate 1:48 minutes late but the captain said an indicator showed and we weren't allowed to taxi. Maintenace came on board did some stuff, then we took off. Because of Tropical storm Debbie we went way east over the ocean. It was still rough though no fault of Jet Blue.
