It’s all sales hype and bravado..wait ’till it’s in service with the airlines and crammed full of seats ..then it may not look so enticing

I bet EK,SQ,IT,QR , VS’s buisness class , and first class seats would be awsome , regarding the economy class well there wont be any difference from the comfort levels of the 777 and the 340’s other then maybe the noise level might be lower .. these airlines would put quite a bit of premium real estate up front so that will be nice.
