Thanks everyone. I will obviously check with the crew before it is used but am relieved it hopefully shouldn’t be a problem. I’ve never thought about her feeling the vibrations more in an aircraft and that may explain why she felt so ill on her last long flight and she couldn’t sleep, that’s very useful to know. As for subtitles in this day and age there is no excuse for not having them as an option for all pre loaded programmes! I’ve already booked the seats via speci assistance, in addition to my deaf daughter my son has ASD so 2 window seats for the children with parents next to each (clubworld) works well for us as it’s slightly less noisy with only familiar people on one side for them.
