This summer time, as I sat on the tarmac at Boston Logan International Airport (BOS) and ready to take off on JetBlue’s inaugural flight from New England to London, the pilot came to visit the intercom with information of a quick delay; however it was excellent news.
You see, we had such a robust tailwind and have been so on schedule a immediate takeoff would trigger us to get into London Gatwick Airport (LGW) too early, in violation of an in a single day flight curfew in place there. So, we might have to attend only a bit. It in all probability “delayed” the flight quarter-hour, however we nonetheless arrived on the bottom at Gatwick an excellent quarter-hour early.
TPG managing editor for information Clint Henderson had a way more inconvenient expertise. Finally on board a Boeing 777-300 on the tarmac at Dallas/Fort Worth International Airport (DFW) in 2018 after a number of delays. He was moving into his business-class pajamas when what seemed to be a reasonably innocent hiccup earlier than a long-haul flight to Hong Kong snowballed quick. The baggage wasn’t all onboard but.
“The passengers have been absolutely loaded,” Henderson mentioned. “But the bags wasn’t.”
That usually minor delay put the aircraft susceptible to arriving in the midst of flight curfew in Hong Kong. Not desirous to threat a violation, the airline ended up canceling the flight, Henderson mentioned.
But what precisely are these “curfews,” and the way may they have an effect on a global flight you are on? Here’s just a few issues to know.
What are flight curfews?
Night flying restrictions, or curfews, are in place at fairly just a few airports abroad, significantly in Europe. Some of the foundations been round for a very long time, however they’ve grown extra widespread in recent times.
As the title suggests, curfews are rules on flights throughout the nighttime hours.
Specifically, it’s a ban or restrict on takeoffs and landings — effectively, scheduled ones, not less than — between set late-night and early-morning hours.

Most typically, these restrictions are inclined to take impact an hour or two earlier than midnight and final till someplace between 4 and seven a.m.
The guidelines usually don’t fully eradicate these late evening and early morning takeoffs and landings, however do search to maintain them to a minimal.
Why do curfews exist?
The sound jet engines make is a typical, driving pressure behind evening flying restrictions.
“You have people living around the airport who complain about noise,” former airline pilot and present University of Nevada-Las Vegas professor Dan Bubb advised TPG. “Airports want to be good neighbors, they don’t want to be noisy neighbors, they don’t want to be bad neighbors.”
But air journey is, in fact, a 24/7 operation, and “an important part of operations at airports around the world,” in keeping with the web site at London Heathrow Airport (LHR), which is likely one of the world’s largest airports, and one with evening flying restrictions.
And some individuals really feel these guidelines are an excessive amount of of a burden.
“It places a lot of unneeded stress on pilots,” Bubb mentioned, noting that, as a former pilot, he worries about pilots having to consider, as he put it, “beating the clock.”
There are exceptions for emergencies
Don’t fear, a curfew is unlikely preserve your aircraft circling for hours on finish, or make your pilot unable to land within the case of an emergency.
Generally, airports have exceptions to their curfew guidelines for emergencies and typically, even for delays, like when there’s dangerous climate.
For occasion, within the United Kingdom, the federal government could make exceptions to permit extra evening takeoffs or landings if delays are prone to result in main congestion on the airport (or hardship for passengers from having their itineraries upended).
Where are curfews in place?
There are quite a few abroad airports with some form of evening flying restriction, that are usually imposed and enforced by some mixture of federal, native and airport authorities.
In addition to the foundations at London’s Heathrow and Gatwick, and Stansted Airport (STN) additionally has a curfew in place at evening.
As an instance of how one such system works, Heathrow operates underneath a “night quota period” between 11:30 p.m. and 6 a.m., throughout which there are limits on plane takeoffs and landings set by the U.Ok.’s Department for Transport. The guidelines usually enable a median of 15 plane takeoffs or landings per evening.
Airports in Budapest and Zurich have additionally evening flying restrictions, and there are fairly just a few airports throughout Germany with curfews, together with Frankfurt Airport (FRA).
It’s not simply Europe, both. Sydney Airport (SYD) in Australia is among the many runways with nighttime restrictions. The guidelines there apply between 11 p.m. and 6 a.m.
Here within the U.S., whereas some airports have units of guidelines or tips surrounding plane noise throughout the late evening and early morning hours, outright restrictions aren’t widespread, significantly because the passage of a 1990 legislation that largely restricted U.S. airports from issuing new noise-based operational restrictions.
Ronald Reagan Washington National Airport (DCA) simply exterior the nation’s capital is one with a self-described “unique” noise rule in impact, which was grandfathered in after that 1990 legislation’s passage. The airport’s governing physique can situation penalties for overly loud plane working between 10 p.m. and 6:59 a.m.
Another instance within the U.S. is available in California, the place the John Wayne Airport (SNA) in Orange County locations a restriction on most arrivals and departures throughout in a single day hours due to noise considerations.
However, the airport factors out that that is definitively not a curfew, and {that a} “majority” of plane working at Reagan throughout these hours are compliant.
How can a curfew have an effect on your flight?
If all goes easily with the timing of your flight, you in all probability received’t ever discover the results of an airport’s curfew. After all, the flights are scheduled in order to adjust to the restrictions.
As I discovered, you can run into a quick delay when flying in a single day to Europe in case you’re operating forward of schedule; that is almost certainly to occur on a flight departing from the East Coast within the early night hours.
You might run into rather more vital disruptions, although in case your plan will get delayed to the purpose the place it may be taking off or touchdown after the “quiet hours” start. That might occur on a long-haul flight to a vacation spot abroad or a short-hop journey in Europe.
“The airline might opt to cancel the flight and rebook the passengers on the next day’s flight,” Bubb defined.
Bottom line
While planes are within the air 24/7 across the globe, curfews are widespread in some components of the world — particularly Europe. Curfews place limits on when planes can take off or land. A curfew received’t preserve a aircraft from touchdown within the midst of an emergency. However, they do clarify the timing of some flights, and why a late-night flight delay might result in a for much longer itinerary disruption whereas overseas.
