The Complete Airport Guide
Airports can seem complicated, particularly when travelling from an unfamiliar airport or connecting through a large international hub. The basic journey is usually straightforward once you understand the different stages.
1. Check Your Flight
Check your airline booking, flight number, departure airport, terminal information and scheduled departure time before leaving for the airport.
2. Get To The Airport
Allow time for traffic, public transport delays, parking, airport transfers and walking between transport areas and the terminal.
3. Check In
Depending on your airline, you may check in online before arriving or use an airport check-in desk or self-service machine.
4. Drop Your Bags
If you have checked luggage, follow your airline's instructions for bag drop or visit the relevant check-in desk.
5. Airport Security
Follow airport security instructions and prepare liquids, electronics and other items according to the airport's current requirements.
6. Find Your Gate
Check airport information screens and airline notifications for your gate. Gates can change, so keep checking until boarding.
How Early Should You Arrive At The Airport?
There is no single arrival time that applies to every airport and flight. Your airline, destination, airport size, security queues, baggage requirements and time of day can all affect how long the journey takes.
Allow extra time when:
- You are travelling internationally.
- You need to check in baggage.
- You are travelling during school holidays or major events.
- You are unfamiliar with the airport.
- You need special assistance.
- You are travelling with young children.
- You have a connecting flight.
- You need to complete additional document or visa checks.
Airport Check-In Explained
Check-in confirms that you are travelling on the flight and allows the airline to issue your boarding pass. Depending on the airline and route, check-in may be available online, through an airline app, at a kiosk or at a staffed desk.
Online Check-In
Complete check-in before travelling when your airline offers it. You may receive a mobile boarding pass or be asked to collect documents at the airport.
Airport Kiosk
Some airports have self-service machines where passengers can check in, print boarding passes or print baggage tags.
Check-In Desk
Staffed desks can handle baggage, documentation checks, special assistance and other issues that cannot be completed online.
Airport Baggage Guide
Baggage rules vary by airline, ticket type, destination and aircraft. Always check your airline's baggage allowance before packing.
Cabin Baggage
Cabin baggage limits can include both size and weight restrictions. Airlines may also limit the number of bags allowed.
Checked Baggage
Checked luggage travels in the aircraft hold. Check the airline's weight, dimensions and number-of-bag allowance before arriving.
Oversized Baggage
Sports equipment, musical instruments and other large items may require advance arrangements and separate handling.
Lost Or Delayed Bags
If your baggage does not arrive, contact the airline's baggage service desk at the airport before leaving the baggage hall.
Airport Security Guide
Security procedures differ between airports and countries. Follow the current instructions displayed at your departure airport rather than relying on old information from previous journeys.
- Have your boarding pass and travel documents ready.
- Follow instructions about liquids and other restricted items.
- Remove items requested by security staff.
- Keep electronics accessible if the airport asks you to remove them.
- Do not pack prohibited items in cabin baggage.
- Allow additional time during busy periods.
- Follow any additional screening instructions.
Airport Codes Explained
You will see airport codes on airline bookings, boarding passes, baggage tags, flight information screens and travel websites.
IATA Codes
IATA airport/location codes are generally three-letter identifiers used extensively in passenger travel, reservations and baggage processes.
Examples include LHR for London Heathrow, CDG for Paris Charles de Gaulle and JFK for New York John F. Kennedy.
ICAO Codes
ICAO location indicators use four letters and are used extensively in aviation and operational environments.
For example, London Heathrow uses the ICAO identifier EGLL.
Why Are They Different?
IATA and ICAO codes serve different purposes. A passenger is more likely to see an IATA code on a booking, while aviation operations commonly use ICAO location indicators.

Connecting Flights And Airport Transfers
A connection means your journey involves more than one flight. The process can vary significantly depending on the airports, airlines, countries and whether the flights are booked together.
Through-Ticket Connection
Flights booked together may provide a coordinated itinerary, although you should still check baggage, terminal and immigration requirements.
Self-Transfer
Separate bookings can require you to collect baggage, leave the secure area, check in again and pass security again.
International Connections
You may need immigration or security checks depending on the countries and airports involved.
