Please people. Only request wheelchair service if you are truly immobile and in need of it for medical reasons. What I witnessed in MIA on our return was truly abuse of that service. Over 15 wheelchairs being used. One person in a chair and a party of 5 accompanying for early boarding. That same person was walking up and down the aisle unassisted numinous times going to the FC restroom. I couldn't believe all the people in wheelchairs at PJIA arrivals that once in arrivals, after retrieving their checked bags, walked out just fine without assistance. I knw some truly need that assistance but in my recent observation some are abusing that service for the wrong reasons.
