Trying to make a decision on whether to stick with our upgraded C seats on UA (should be new config) to SYD or switch over to V Australia and try their C at the promotional fare. It appears as though the 23.5" seat width reported by UA is with the armrest down--basic seat width is 19", which makes the VA seat a bit wider (20.5") to start. But both seats seem like a tight squeeze. Thanks for the input, stargold.
