International Flight Boarding Process


Check-in time for International Flights

This one is the crucial step of international travel, as many international check-in counters between 60 to 9 minutes before departure and some even earlier, depending on the destination. Even if you complete online check-in, you are still required to come early to the airport because you must undergo document verifications and other processes. Let’s check out counter check-in and online check-in:

Counter Check-in

Lots of international airlines close their check-in counter 90 minutes before departure for certain destinations, and if you arrive late:

  • You will not be allowed
  • Ticket marked as no show

Online Check-in

Even with online check-in, you still:

  • Verification of passport and visa is mandatory
  • Boarding pass verification is required multiple times
  • Time for baggage drop

If you made an online check-in, it does not eliminate the need for early airport arrival.

Immigration and Passport

For international flights, immigration is the most consuming process in departures, and this depends on the number of passengers, the size of the airport, staffing, and destination regulations. In the seasonal time, it takes from 30 minutes to over an hour. Here are some factors that affect immigration time:

  • Passenger volume
  • Number of international flights departing
  • Immigration counters
  • Country regulations where you are travelling.

Security checks

These procedures are very important for safety and take time, especially in international flights as compared to domestic flights. In this, you can take up to 15 to 45 minutes, depending on airport size. For smooth security screening, you may be required to:

  • Remove electronic devices from bags
  • You can go for secondary security checks
  • Go for additional baggage screening

Boarding Time

Boarding gates close around 20 to 30 minutes before takeoff of the flight, and Airlines strictly follow the gate closure time. and if you arrive late and see that your flight is still parked at the airport, then you will not be allowed to board. That's why early arrival ensures you are present at the boarding gate well in advance.

Airport Size

Well, airport size also matters because in a large international airport, there are thousands of passengers, and this means:

  • Long queue
  • Walking distance
  • Confusion about the gates
  • Time-consuming
  • More congestion with multiple checkpoints

In a small airport, there are fewer queues, and the immigration counter is limited, which can cause delays

Seasonal time

When there is seasonal time, you should arrive earlier than 3 hours because during peak seasons, there will be long check-in queues, slower immigration processing, and increased security wait times. Always be prepared for travelling during:

  • Festival periods
  • Weekends
  • Early morning or late nights
  • Holiday seasons
  • Summer vacations

In some situations that need extra time, you should always keep in mind

  • Travellers who are travelling first time internationally you may need extra time for guidance and to avoid confusion.
  • Travelling with family or children requires more time, and when you travel with elderly passengers or large groups
  • Travelling to high-security destinations requires detailed visa verification, additional airline checks, and extra documentation.

Having no checked baggage, still need to reach early?
