These timings are approximate and can vary according to the airline, weather, air traffic and operating conditions.
Boston is one hour ahead of Chicago. Chicago follows Central Time, while Boston uses Eastern Time.
For example, when it is 8:00 AM in Chicago, it is 9:00 AM in Boston.
Both cities observe daylight saving time on the same schedule, so the one-hour difference remains consistent throughout the year.
Flight departure times are shown in Chicago local time, while arrival times appear according to Boston local time. Travelers should therefore account for the one-hour change when reading their itinerary.
