'OITNB' Star Uzo Aduba Does Awesome Good Deed After Emmy Win

Uzo Aduba flew coach to NYC after winning a Best Supporting Actress Emmy, but not because she didn't want to spring for a first class ticket ... she gave her seat to a woman in pain ... her mom.

The "Orange is the New Black" star got on the plane Monday and settled into her "flatbed seat" in the front of the plane. But there was a problem.

Seems whoever booked the flight got her a first class ticket but not the others in her party, including her mom, who had surgery and is walking with a cane.

Uzo walked back to coach to see her mom and then did the switch. She sat there for 5 hours, in the company of her Emmy.

Lucky mom to have Uzo as a daughter.
