Sorry if this isn't the correct thread but maybe someone knows the answer: do the armrests in Economy on BA's A350, especially aisle seats, go all the way up? I've been on some flights with KLM where the armrest only goes up to about 45 degrees and can't be stowed up and parallel with the seat back. I ask because my mother has mobility issues and getting her into economy seats without raising the armrest fully is extremely difficult.

Many thanks for any information folks can provide...
