Counting work hours during travel depends largely on your company's policy and local labor laws, such as the Fair Labor Standards Act (FLSA) in the U.S. Generally, for "non-exempt" employees, travel time that takes place during their normal work hours (even on weekends) is typically considered compensable work time. For example, if you normally work 9:00 AM to 5:00 PM and you spend those hours on a plane on a Sunday, those hours should be counted. However, the time spent traveling outside of regular work hours as a passenger (like on a late-night flight) is often not considered "work time" unless you are actually performing work tasks while in transit, such as answering emails or preparing a presentation. For "exempt" or salaried employees, the distinction is usually less rigid, as they are paid for their output rather than their hours; however, many professionals still track "travel hours" separately to account for burnout or to bill clients for travel time. It is a best practice to keep a detailed log of your departure and arrival times, as well as any time spent working at the airport or on the plane, to ensure you are accurately reflecting your professional contribution and complying with your employer's expectations.
