Q: In the competitive airline industry, even small flight delays matter. They can cascade across the nation, affecting “hundreds, if not thousands, of passengers,” Mr. Isom said in an interview. It’s not just about the coffee, he said, it’s “the most financially sound way to run an airline.”

 Mr. Isom came to American in its 2013 merger with US Airways, where he helped to achieve one of the industry’s best on-time departure records, which means taking off within 15 minutes of the scheduled time. American could use help on that score. At 83 percent for the first three months of the year, American ranked between two of its main rivals, Delta Air Lines (86 percent) and United Airlines (81 percent), according to the Department of Transportation. 
  
 Mr. Isom declined to say precisely how many of American’s delays are caused by broken coffee makers. The Department of Transportation, which tracks delays, said it couldn’t provide that level of detail. 
  
 In his quest to get American’s planes off the ground on time, Mr. Isom is looking not only at coffee makers but also at other seemingly mundane delay-causing problems, such as spills on seats. Spills on cloth upholstery can delay a flight because the crew must remove the seat cushion and replace it with a dry one. Economy travelers can expect to see more “synthetic leather” seat covers, which have superior wipeability. 
  
 Onboard coffee machines are trickier. They cost anywhere from $7,000 to $20,000 apiece. And they are electrical, so if one isn’t working, the ground crew needs to make sure there’s not a problem with the circuitry that could cause a fire or other hazard. 
  
 “You can’t just put Mr. Coffee in an airline,” said Jeff Lowe, president of Aviation Fabricators, a certified airplane repair station in Clinton, Mo. “You have to do all kinds of engineering and analysis and provide test results to the F.A.A. to get approval.” 
  
 The Federal Aviation Administration requires coffee makers to have safety features like circuit breakers and wiring insulation to protect against onboard fires. So when a coffee machine misbehaves, maintenance crews must inspect it to ensure there is no risk. 
  
 Other special features include latches to ensure that the coffeepot does not shake loose during turbulence. These elaborately engineered details mean there is more that can go wrong.

 Airplane safety rules try to anticipate problems because if something goes wrong midflight, there’s little room for error. For instance, even though smoking cigarettes has been banned since the 1990s, planes still must have ashtrays in the lavatories. Because if someone does smoke in there, they have a place to put the cigarette other than the trash bin, which is full of flammable paper.

 When a coffee machine breaks down, often it can simply be replaced by spares kept on hand for that purpose. If that’s not possible, the plane can still take off, but only after mechanics disable the coffee machine by turning the water off and cutting the power. 
  
 This, though, can cause a new set of problems for airlines. Passengers expect on-time departures — but they expect coffee too. “@AmericanAir- seriously no coffee on a my morning fly 5797 to ONT? Doesn’t that violate a law or something?” wrote Tim Swearingen, a technical project manager based in Phoenix, on Twitter a few days ago. 
  
 Reached by phone, Mr. Swearingen added this thought: “And why would you wait until I’m on the plane to announce that? I would have gone to Starbucks.” 
  
 Even the water is complicated in an airliner and can contribute to breakdowns. Marcos Jimenez, an engineer at Zodiac Aerospace who has developed patented coffee-maker technology, said there were two main types of machines: those that use water from an airplane’s water reservoir, and those that require a flight attendant to pour filtered, bottled water into the machine. 
  
 Most commercial airlines use machines hooked up to a water tank. “Because it’s in a tank, they have to take particular care to make sure the water is not growing bacteria and whatnot. So they treat it with chemicals, kind of like a pool,” he said. 
  
 These chemicals, along with minerals in the water, can cause residue to build up in the machinery. Clogs can cause the machine to break down, particularly if maintenance crews don’t clean them often enough, Mr. Jimenez said. “I don’t drink the coffee unless I know the water’s coming from a bottle.” 
  
 Delta and United acknowledge that coffee makers can cause trouble, though they do not seem as focused on it as American is. “We do have some delays due to coffee maker problems from time to time, but it’s not a prevalent cause,” said Jonathan Guerin, a United spokesman. He noted, however, that United’s maintenance crews recently increased the frequency of checks on coffee makers specifically to reduce delays. 
  
 American is working with B/E Aerospace, a manufacturer of aircraft cabin products, to replace malfunctioning coffee makers on many of its planes, at thousands of dollars each. American’s Boeing 737s, which make up about a third of its fleet, typically have four of the machines on board. Larger planes like the Boeing 777, which usually flies international routes, may have more than a dozen coffee makers.

 If the overhaul is effective, it might cut down on the number of complaints from passengers like Darren McGrady. 
  
 Mr. McGrady, a personal chef based in Dallas according to his Twitter bio, boarded a 6:45 a.m. flight in April, only to find his departure delayed by a broken coffee maker. He complained about that on Twitter, and American’s corporate account replied: “We’ll get the coffee maker up and running so we can have you on your way!” 
  
 A few minutes later, Mr. McGrady tweeted again, this time with a photo of an empty galley — no mechanics in sight. “I can see technicians swarming around the coffee machine trying to fix it,” he wrote. 
  
 American followed up: “It’s all set now! You’ll be wheels up soon.” 
  
 “You can sit and wait on an airplane for the dumbest things,” said Mr. Lowe at Aviation Fabricators. But he takes a philosophical view. 
  
 “They have to wait for some guy in maintenance to say, ‘It’s O.K.,”’ Mr. Lowe said. “And frankly, that’s probably the way it ought to be.” ||||| Tweet with a location

 Eoin Gill had four flights on American Airlines last week, all significantly delayed, and he missed his most-desired meeting of the week: getting home to see his two small children on Friday night. 
  
 Frequent fliers "are getting mutinous," said Mr. Gill, a Dallas banker. "They all have horror stories."

 A broken coffee pot may be just that -- a broken coffee pot. However, coffee pots are electrically powered; as a professional pilot, I would point out that the reason a pot isn't working may go well beyond the pot itself to the incredibly complex nature of an aircraft's electrical system and may possibly indicate a deeper and more serious problem than the pot itself. Now, if you were a passenger on that aircraft with the broken coffee pot, would you like to risk an in-flight electrical fire for the sake of not having your flight delayed, or would you like the pilot to get maintenance personnel to confirm the reason for the pot's not working prior to takeoff?

A:
Running late for a flight? Cross your fingers that the plane's coffeemaker is broken. An "inordinate amount of coffeemaker problems" are causing flight delays, American Airlines' chief of operations says—and causing passengers to lose their lids. The New York Times reports defective coffeemakers require a thorough check since any issues could suggest a problem with the plane's circuitry. Airlines don't keep track of such delays specifically, but Delta and United also acknowledge that they do happen. A Twitter user says her American flight last month was delayed 45 minutes thanks to a faulty coffeemaker. A man says his hourlong flight in November was delayed 40 minutes for the same reason. And this isn't anything new: A Dallas banker told the Wall Street Journal in 2012 that a leaky coffeepot also grounded one of his flights. Because planes' coffeemakers are so elaborate—they include circuit breakers, wiring insulation, and special latches to hold the pot in place, and they're sometimes hooked up to water tanks treated with chemicals—plenty of things can go wrong. Of course, you want officials to identify a problem that might present a fire risk. But even the smallest of issues can require the machine to be disabled (no water or power) or swapped for a functional one. Airlines realize this is an issue: United recently increased checks on coffeemakers, while American is considering replacing all of its machines, which can cost up to $20,000 apiece. In the meantime, know that flight delays blamed on coffeemakers are for your own safety. As a pilot wrote to the Times in 2002, it's not worth risking "an in-flight electrical fire for the sake of not having your flight delayed." (See where flights are delayed most.)
