Thanks for all your help so far.

she is allergic to soya and it gives her headaches which can last for hours or even a few days.

seems v difficult to see what comes in the special meals to make sure that wouldn't trigger the reaction.

Sadly some of the regular loaded meals would probably be fine if they didnt have the sauce already on the food. Also a shame I can't order an all day breakfast….

If BA ever got back to pre ordering meals on flights this would also be a good help for us to make sure there was something suitable.
