I am delighted to once again contribute to Celebrated Living’s special Gift Guide issue. As you know, the season of giving and the beautiful scenery that comes with winter make for a joyful time, but it can be stressful, too, particularly when winter weather disrupts our plans. I’m guessing you have heard the old expression, “I f you don’t like the weather in (choose a location), just wait a few minutes.” An American Airlines variation of that cliché might be, “If you don’t like the weather, hop on a plane,” because given our vast international network, at any given moment our customers and our employees around the globe are experiencing wildly varying conditions. During the winter months, for example, you might board an AA aircraft in Chicago amid snow and ice and be welcomed in Delhi by temperatures in the 70s and 80s. If you’re flying with us today in North America, Europe, or Asia, chances are it’s pretty cold right now. In this column, I would like to tell you about some of the steps we take to adjust to Old Man Winter’s arrival.

Perhaps the most basic thing we do is change our schedule. We increase service to Florida, the Caribbean, and other destinations people from northern latitudes visit to escape the cold. We also add service to winter-sports destinations such as Vail and Steamboat Springs in Colorado — places we serve less often or not at all in warmer months — to delight skiers and snowboarders. Changes in the weather affect our schedule in other ways too. The polar jet stream — a strong air current 22,000 to 39,000 feet above North America, Europe, and Asia — flows from west to east more strongly in the winter than in the summer. This slows westbound flights and slightly speeds eastbound trips. For example, our New York-to-L.A. “transcons” take 30 minutes longer in winter than in summer. Conversely, eastbound transcons are about 15 minutes faster in winter. Similar changes occur on trans- Atlantic and trans-Pacific flights.

Aircraft are designed for the cold because it’s always winter at cruise altitude. As a rough rule of thumb, air temperature drops about 3.5 degrees Fahrenheit for every thousand-foot rise in altitude, to a limit of about 70 degrees below zero. Whether our planes are on the ground, climbing or descending through cold temperatures, or flying at cruise altitude, we must keep key parts warm. During flight, we circulate hot air from the engines to keep many parts of our planes warm and dry. Our aircraft windshields have built-in heating elements, too, akin to an auto’s rear-window defroster. Our mothers always reminded us to “close the door,” and that directive certainly applies to airplanes. This is especially important when planes are parked overnight, when we also drain water lines and remove galley coffeemakers to prevent pipes from freezing and bursting.

In some parts of our network, handling winter precipitation is a near-daily challenge. Safe flight depends on an aircraft having its wings, engines, and control surfaces free of freezing rain, ice, and snow, so naturally, we spend a lot of time, energy, and money keeping all these surfaces clean. At our Chicago O’Hare hub, for example, we have a fleet of new deicing trucks, which have cut deicing times in half and have reduced our use of deicing fluid by 75 percent. These “smart trucks” mix the necessary fluids precisely based on temperature, heat the fluid as it’s needed (rather than in a tank), and have booms that are able to get closer to our aircraft. While new technology is great, it is ultimately the experience and know-how of our people (as an airline, we have more than 80 winters under our belts), along with the sheer fortitude required to brave the elements, that keep our operation humming through all sorts of weather.

Winter is upon us (for those of us in the Northern Hemisphere, anyway), and my hope, of course, is that you will never get caught in a weather delay. But if you do, I am sure you will appreciate the many people working hard to make absolutely sure your aircraft is ready to fly safely. Speaking of appreciation, let me close as always by thanking you, on behalf of every member of our team — at every latitude — for flying with us today. Remember, if you don’t like the weather where you are, don’t wait! Let us help.
