I left on Wednesday, had wheelchair assistance, and was at the gate in less than 30 minutes from arrival. I also used the boarding pass on my phone and departed from a B gate. The fabulous attendant wheeled me to the plane; it was close enough that people walked - no bus. There was a ramp to the plane, not stairs. My attendant even took my bag up the ramp for me and put it in the overhead. He was a real sweetie and gave me a big hug before he left the plane. As others have said, those SXM wheelchair attendants could teach US attendants a thing or two.
