The +1 notation on a flight itinerary indicates that the flight arrives on the calendar day after the departure date. This is common on long-haul international flights, particularly those traveling eastbound (such as from New York to London) or across the International Date Line. For example, if you depart on Friday at 9:00 PM and your arrival is marked "7:00 AM +1," you will actually land on Saturday morning. It does not necessarily mean the flight is 24 hours long; rather, it accounts for the combination of flight duration and time zone shifts. Occasionally, you may see a +2, indicating a two-day jump, or a -1, which occurs when flying westbound from Asia to the Americas, where you "gain" a day and arrive on the same calendar date you left, or even the day before. Always double-check this when booking hotels or car rentals to ensure your arrival date matches your check-in.
