  “ Did you know that a flight from New York City to Houston, Texas is over an hour longer today than if you took the same flight in 1973? Now it takes about three hours and 50 minutes, but 43 years ago it would have taken 2 hours and 37 minutes. What gives?

Surprisingly, flight time is calculated from when the aircraft releases the parking brake (on push back) to when it sets the brake on arrival to the gate,” commercial pilot Chris Cooke told Travel + Leisure. “All that waiting in line during taxi and takeoff counts toward flight time.

Not surprisingly, saving money is another reason flights take longer today. “Airlines are able to save millions per year by flying slower," reveals a video from Business Insider. ”

Are You Being Told the Truth about Flight Times?

A study which says they are skewing flight times:

Are you being told the truth about flight times?

  “ Passenger jets have never been more advanced. With Boeing’s 787 Dreamliner, introduced in 2011, leading the charge, and new models like the 737 MAX and the Airbus A320neo following in its wake, the aircraft on which we travel are safer, smoother, quieter and more fuel efficient than ever.

They also appear perfectly capable of flying faster than their predecessors. Just last month the low-cost carrier Norwegian issued a celebratory press release after one of its 787 Dreamliners whizzed from John F. Kennedy International Airport in New York to London Gatwick in five hours and 13 minutes, setting a new transatlantic record for a subsonic plane. That’s three minutes quicker than the previous best time set by British Airways in January 2015.

So why, record-breaking feats notwithstanding, are airlines claiming it takes longer and longer to fly from A to B?

That’s according to research by OAG, the aviation analyst, carried out for Telegraph Travel. It found that over the last couple of decades, despite new technology, scheduled flight times - ie. how long an airline estimates it will take to complete a journey - have actually increased by as much as 50 per cent.

Looking at Europe’s busiest international route, for example - Heathrow to Dublin - it found that in 1996 the vast majority of airlines published a scheduled flight time of between 60 and 74 minutes. Fast forward 22 years and almost all claim the journey takes between 75 and 89 minutes, while a handful bank on 90 minutes or more. ”
