Save this Post. 3. Re: Rear facing seats in United 747-400 business class. Jan 14, 2013, 7:17 PM. I would still go with the upper deck, even with the 3 less length. The main business cabin on the 744 feels rather cramped in business class. The upper deck seats are much quieter and private. You also have the additional storage compartments along the window side. I have travelled on this plane, but in forward facing seats. We could only see the passengers across the aisle, not those in front of us. The upper deck was quiet, the side storage compartments excellent and the seat pitch more than adequate.
