Although in a perfect world Air France should have immediately stopped what they were doing to summon a doctor for you, I believe that you need to accept a little more responsibility for this situation. Diabetes is not a heart attack - - it's a diagnosed medical condition for which the patient is educated on maintenance procedures. It is your responsibility to anticipate various situations (such as airline delays if you travel) that may arise and be prepared for them in terms of medication and food (such as health bars, etc.).

The fact that you were not prepared to handle your own health situation and that your wife and two infants were crying does not appear to be justification for a refund.
