First-class airfare on average costs seventy percent more than economy airfare. According to Business Insider, "an American Airlines economy flight from John F. Kennedy Airport in New York City to Heathrow Airport in the UK in July 2018 is $915. If you're flying first class on the same airline, that cost increases to $5,407." Fortunately, a lot of the perks offered in first class are worth it. Passengers are offered high class food and beautiful tech and sleeping accommodation.
