Dear Bill, An international flight requires that you arrive and report at the boarding gate at least 2 hours before take-off time. However, the airline itself may give guidance on their website. If you are like most people and all you need is to focus on the flight without reading tons of literature, please always be at the airport 2 hours before take-off for any international flight, and 1 hour for local flights. Good luck.
2.5-3 hours before take off
