First-class air travel is in decline
Most “first-class” passengers on these routes now sit in seats with the same legroom as economy passengers, albeit with an empty middle seat, and make do with extras such as lounge access, and food and drink. In other words, flyers begin to think economy on Emirates, say, is fancier than on other airlines by association with features in its first class, such as in-flight showers. First-class passengers want to sleep and eat when they choose, not on a timetable set by cabin crew, as often happens in business class, says Joost Heymeijer, head of Emirates Inflight Catering.
