Guys, I am flying from PHL to SFO direct during the labor day weekend. I wanna double check the SeatGuru to figure whether I wanna go for the Premier Travel options. I looked up the website but I didn't see any information regarding what aircraft I am getting on. It's United 0447, which is the best info I can get. Is that Boeing or Airbus? I tried one from PHL to LAX direct before with the Premier Travel. Seems like it's 3-cabin aircraft, right? Any info will be really appreciated!
