Sorry to disagree roadrunner21. As you say the lady is not disabled in the eyes of the law. She is at best described as temporarily incapacitated and I doubt it very much if she was covered by ADA legislation. As other OPs have stated, there is an inherent duty of care on the part of EK to this lady and to ensure any health risks to her are minimised. Are you sure this is not a try-on by someone with a long journey travelling with two very young kids? As someone has posted, if the lady insists on travelling, the best bet would be to pay for the upgrade to J. I would then have no qualms about EK upgrading her to F to make her journey more comfortable.
