How Much Does It Cost To Upgrade To Business Class On A Transoceanic Flight?

Long-haul flying involves hours over the Atlantic or Pacific Ocean, and to offer more comfort to high-paying customers, airlines have invested significant sums in luxurious premium cabins. By far the largest cabin on most transoceanic flights aside from economy is business class, which sits above premium economy and below first class, although few airlines still offer a true international first-class product today. This means that, in most cases, business class is the best way to fly over the ocean.
