The only problem I have with this is we're just picking which disabilities are politically correct. A person who flies in a wheelchair takes up more space and requires alot more time and manpower with flight attendants assisting him, yet people would scream bloody murder if he was charged extra for that. I think you should have one policy for everyone and stick by it and not decide which disabilities deserve special treatment and which don't. If you want to charge fat people extra fine, but also charge people in wheelchairs, the blind, and anyone else who requires special assistance/measures.

I don't think people in wheelchairs fly in them. I think they sit in a seat and have the wheelchair put in storage. The wheelchair might take up luggage space but that is very different from taking up a second seat.
