Reid had a brief loan spell at Loftus Road two seasons ago and made his Baggies debut there in a 3-1 defeat.
"All the teams that have come up have got good sides," he told the WBA website.
"QPR ran away with the league in the end.
"Loftus Road is a tough place to go.
"It's a tight little pitch and the crowd really get behind them.
"I went on loan there but got injured in my second game, so I have disappointing memories of that.
"And, again, I have disappointing memories from my first game for Albion there!
"Hopefully, I can get a positive result this time.
"The newly-promoted teams will be full of confidence to start with but they are teams we'll be looking to get results against."
