I am fully qualified to fly space-a, but I require a wheel chair to get around. Can I still fly Space-A?

Regretfully, no. the following is extracted from an AMC GRAM PASSENGER TRAVEL INFORMATION dated 21 Jun 2016:

PASSENGERS WITH NON-APPARENT HANDICAPS: Passengers with non-apparent handicaps including hearing, asthma, or pacemakers should advise a passenger service agent during check-in. Passengers with a handicap preventing movement under their own power are not permitted on AMC aircraft.

See the original document here. Please see page 2, paragraph 5 titled, “PASSENGERS WITH NON-APPARENT HANDICAPS”
