The One With Ross's Wedding, part 2 - S4-E24
Corrected entry: When Rachel is on the plane, it is shown from the outside to be a Boeing 747. When they get inside it shows only 2 seats over by the window. A 747 has a seating configuration of 3-4-3, with 3 seats by the window.

Corrected entry: One best man (Joey) walks down the aisle with the mother of the bride and the other (Chandler) comes in with Monica which is completely wrong. The best man (or men) should be at the front of the venue with the groom - they are there to support him.
Correction: And there "should" be only one best man. There aren't any laws in weddings, so Ross can change it however he wants.
The One With Ross's Wedding, part 2 - S4-E24
Corrected entry: In the scene where Rachel is on the plane telling the guy across the aisle about the history of her and Ross, the guy sitting beside her interrupts and says something like, "You are a horrible horrible person". If you look at his watch throughout the scene, it switches from having a leather strap (brown or black), to having a metal band, and then back again.
Correction: His watch consistently has a dark leather strap, it never changes.
Correction: Virgin Atlantic uses 2-4-2 in Premium Economy, so 3-4-3 is not a rule, although it's the most common in economy on a 747. Surely the set is not an exact copy of a real plane, but the seating configuration is ok.
