EIDAH suggests...
You can say what you like about Ryanir but I am sure they would never break the IAA's rules its not in there interest they would lose there operating license.
An incapacitated 80 year old and a 10 year old child sitting in an Emergency Exit Row.??
What IAA rule allows that.
As for non-aviation background, you are quite right EIDAH, I'm retired now after 35 years at the front end of BA wide-bodied and loving it.
Perhaps that's why, EIDAH, having seen how the job should be done, I am less than impressed with the standard of Ryanair Cabin Crew
