I have to catch a flight 8:45 in the morning what time I should be there

3hrs for international and 2hrs for national

At least 3 hrs before the actual departure of international flights.

Perfect question. When you plan to get to the Inernational Airport, you must be there in the very early hour before the main schedule of the due date expires. Here's the plan. The best thing to complete this is to go to sleep immediately, pack your personal items, get your suit case ready before the morning time, and have your documental citizenship set. So that there's no penalty issues. Rather if is your home or best hotel. In 6:00 or 7:00 AM. Make sure you have your Passport with you, get your ride, bring your luggages, Airline Tickets and Boarding Pass. Never lose anything behind. When you finally there, Go there quickly without delay or hesitation. [Important Warning] Try to be there in time before it's gone. Don't miss it plus they have to move on. If you miss it, you'll be stuck and lose the game for automatic lost. Once you're at the gates, give them your Tickets, Passport, and enter the plane of your choice. When you're in, you'll be on your way to the country of adventure.👍
