United has a few configurations for 777 economy seating - a 3-3-3 configuration with 18.3" of width and a 3-4-3 with 17.1" of width. I've flown the 3-4-3 one and will never fly it again, it is super cramped, and even the few inches of extra leg room in economy plus can't make up for the narrow seats. So being a wide/narrow body jet doesn't really relate to seat width, it's all based on how many seats the carrier can cram in. https://www.seatguru.com/airlines/United_Airlines/United_Airlines_Boeing_777-200_6.php https://www.seatguru.com/airlines/United_Airlines/United_Air... https://www.seatguru.com/airlines/United_Airlines/United_Airlines_Boeing_777-200_9.php https://www.seatguru.com/airlines/United_Airlines/United_Air...
