Answer: ''International airport procedures can be long and stressful, especially if you’re a first-time traveller or have anxiety. To better understand the airport process, here’s a step-by-step guide which will help you know what to do and find your plane with ease. Plus, when you’ve done it once there’ll be nothing stopping you from travelling again and again and again…
1. Master the check-in process
For international flights, you should arrive 3 hours before your departure time. At the airport, you’ll need to check in; this can be done at the airline desk or online, however consider checking in at the airport for your first time – essentially, this process confirms your booking with the airline.
At the counter, you will:
Have your passport scanned.
Receive your boarding passes* and baggage claim card (do not lose your boarding pass!)
Weigh bags and hand over any checked luggage (carry-on luggage is subject to size limitations)
*If you need to change planes and have booked flights on separate tickets, you will need to acquire your next boarding pass from the airline’s transfer desk at the following airport! You may also need to collect your checked luggage.
Once you’ve completed check in, follow the ‘DEPARTURE GATES’ sign.
2. Get through the security screening
Security screenings are mandatory. For this process, your items are placed in trays and x-rayed to search for any dangerous goods or prohibited items. Items in these categories differ for each country so it is important that you research custom laws for both your destination and all transit airports. Security queues can be very long, so prep for your screening to be as quick as possible:
Remove jackets, belts and all metal items
Empty your pockets
Make sure your drinking water bottle is empty or it may be confiscated
Put everything, including documents, into your bag
Place your LAG* bag and laptop in a separate tray
Proceed through the metal detector
Comply with random searches (pat downs, body x-rays, bag searches)
After security, follow the route to customs!
*LAGs are liquids, aerosols and gels heavily restricted to 100mL/grams or less per item which must be placed in one clear, re-sealable plastic bag. This includes creams, deodorants and hand sanitisers – keep it in hand’s reach so you won’t be digging through your backpack for it."
