Ice Cube and his entourage flew first class from SXSW -- but his "Friday" co-star was forced to sit coach!

TMZ cameras caught the crew when they arrived back at LAX, but a spy on the plane says the guy who "got knocked the f**k out" in the 1995 flick was the only one who couldn't enjoy the finger bowls, fresh cookies and leather seats.
