I'm looking at my flights on ExpertFlyer at the mo and I'm confused. My flight to DXB on 22nd Oct shows a slightly different configuration in row 39 to my flight from DXB on 27th Oct, yet both are operated by a 777. Are there different seating plans for different 777's (apart from 3 and 4 class). FYI my flight on 22nd is at 1240pm, and my return on 27th is at 10am
