We flew to PHX for appointments at the Mayo Clinic. Upon departure my wife was in a wheelchair and we had to get our boarding passes at the ticket counter due to a change in our schedule. The Southwest employee asked my wife a couple questions, like, can you walk the jetway and do you need a special seat.......what's a special seat on a 727 with one class of service? My crippled wife apparently gave a wrong answer about being able to walk down the jetway instead of using a wheelchair. Because of that, instead of getting a pre-board pass we ended up in row 17 which necessitated my poor wife who was in great discomfort and pain, walking an unnecessarily long way. I pleaded with the ticket agent and explained my wife's medical condition, but no, she had given a wrong answer.....because she is a trooper and doesn't like anyone to think she is a slacker, even though she was in pain at the time. So it goes, some Southwest employees have empathy and common sense, and others have no clue or compassion for other peoples difficulties. Otherwise, the flight was uneventful and on time.
