Blind pax

[Pugachev Cobra]

Hello,

I would like to know in your airline what is the common procedure for blind passengers.

Are the number of blind passengers limited per flight? If yes, based on what?

I've heard of flights with more than 190 blind passengers, so I can't think of a good reason to reject a passenger based on its visual disability.

Where does an airline crosses the line from safety to discrimination?

What are you views on this subject?

Thanks!
