Flew LAX-LAS on Feb 10. Forget the flight number, 8:20PMish departure. LUS321 with 16 F seats, 3 empty.

Saw a remarkable scene when boarding. A rather large pax was in a wheelchair - had to be 250# plus. His companion got him out of the chair facing him and lifted him up, so that the disabled pax's legs are looped under the companion's arms and his arms are around the companion's head - and he carried him from the edge of the jetbridge to his seat, which admittedly was 1D so the closest to the door. The companion wasn't that large an individual. Companion eventually sat down in 1F. I didn't stick around to see how they got him off.
