It'll take you longer to get there now.
Ryanair has instructed its pilots to stick to a 600mph speed limit, which will save the carrier on fuel costs but also make trips take longer.
It's not just exploitative airlines like Ryanair—although it gets the bad press for it. JetBlue did the same thing in 2008 and saved $13.6 million.
In 2011, Cunard Line's Queen Mary 2 quietly increased most of its New York/Southampton trips by a day. It once took six, and now, you disembark a full week after you got on. The ship is capable of making the crossing in under four days, but Carnival, which owns the ship, runs it slower to save on costs. Happily for the publically traded company, that means two more days of on-board spending for guests.
