Trouble is, the Doctor's perception of whether a person meets certain criteria will always differ from the perception of the airline.
So the letter signed by the family doctor says "John Smith would benefit from a seat with more legroom" - well wouldn't we all. The only problem is that generally the seats with extra leg room will be in the exit row & as John Smith has a walking stick, hearing aid etc, he's not eligible to sit there anyway. Then there's the letter that says "John Smith would benefit from a seat in Business Class"!!!
How do you know just because there's a comment in a booking saying someone is 6'5" that they
are that tall? I've see plenty of people allegedly that height then when they turn up an the airport they're about 5'6"
I still want to know if Adam Menzies the person at the centre of this article, travelled to the US with his wife
and child? Because if he did, that would really explain a lot of things & yes, plenty of people with infants ask for the exit row.
