The time it takes to get to the airport before your flight departs depends on the type of flight and the airport you're flying from. Here are some general guidelines:

1. Domestic Flights

• Arrive at least 1.5 to 2 hours before departure: For domestic flights, you should arrive at the airport at least 1.5 to 2 hours before departure. This will give you enough time to check in, drop off your luggage, and go through security.

2. International Flights

• Arrive at least 2.5 to 3 hours before departure: For international flights, you should arrive at the airport at least 2.5 to 3 hours before departure. Checking in for international flights is often more complicated, involves passport and visa checks, and can take longer at security checkpoints.

3. Things to remember when arriving at the airport

• Peak hours: If you are flying during peak hours or from major airports, you may need extra time as check-in counters and security checkpoints can be crowded.
• Special procedures: If you have special requests such as oversized luggage, fragile luggage, or need assistance, please arrive early to allow enough time for processing.

• Online check-in: If you have checked in online and are only traveling with carry-on luggage, you may arrive at the airport a little later, but you should still arrive at least 1 hour in advance for domestic flights and 2 hours in advance for international flights.
