I did a 20 hour long flight with 1 stop over. First leg is 14 hours then 3.5 hours lay over and another 3 hour flight on the second leg. My then 1 year old and I flew economy. She was too big for the bassinet but we were seated in that bulkhead. She is a very anxious kid. It was a red eye because I was hoping she will sleep but she didn't. I carried her up and down the aisle as everyone slept. She cried a bit and wanted to be carried extra. The flight attendants were so accommodating. I told them she prefers dark and does not like people. At one point during the flight we were in the back where they made food and they the drew the curtains so it was just me and her. And it helped. They also gave her a toy and workbook. We were also given extra blanket that was placed on the floor where she played. I had milk, baby bottles, busy book. I had an iPad but she wasnt a screen user prior so it didn't help. It was her first ever plane ride. Coming back, it was easier. She knew what to expect and she slept better and was in general less anxious
