The pinnacle of air travel, first class travel is reserved for celebrities and the super-rich (and the super-lucky). Think all the perks from business, lathered with a ridiculously thick layer of luxury. However, aside from privacy, and seat size (bear in mind that many first class flights don’t so much have seats, as individual suites), there’s not that much they can do to make first stand out markedly from business. One noticeable difference is price, with seats costing up to five times as much as business class seats. Ouch.
