Hi, I have done most of my flying in Business class and have not flown First Class for a long time. My question here for all the experts are "What is the big difference between Business and First Class and is the extra price worth it for International flights?" I know that First Class seats are bigger however I always thought that the Business class seat was just fine. Just looking for other differences. Thanks

PS, I didn't know where to post this question so I posted here.
