On an airline ticket or flight itinerary, a "+2" next to the arrival time indicates that the flight arrives two calendar days after the departure date. This notation is common on "ultra-long-haul" flights that cross the International Date Line or multiple time zones while traveling east, such as a flight from New York to Singapore or Sydney. For example, if you depart on a Saturday afternoon and see a "+2" arrival time of 6:00 AM, you will actually land on Monday morning. It is important to note that a "+2" does not mean the flight duration is 48 hours; rather, it is a result of the combination of actual flight time (often 15–18 hours) and the "losing" of hours as you move across time zones. Travelers must be extremely careful when booking hotels or car rentals for "+2" arrivals to ensure their reservations align with the actual day they land, as it is a frequent source of "day-count" errors for first-time international flyers.
