1) To check your flight number and departure time, you should enter the airport and look at the departures board. The departures board is usually located in the main terminal area and displays the flight information for all departing flights. Find the display corresponding to your airline or flight number, and it will show you the departure time and gate number for your flight.

2) To weigh your luggage and ensure that it doesn't exceed the allowed weight limit, go to the check-in desk. The check-in desks are typically located near the entrance of the airport or in a designated check-in area. Present your luggage to the airline staff at the desk, and they will weigh it using a weighing scale. Make sure that your luggage does not exceed the specified weight limit, which is usually mentioned in the airline's baggage policy. If your baggage exceeds the weight limit, you may have to pay for the excess baggage, which means you'll have to pay an additional fee for the extra weight.

3) After checking in your luggage, you will receive a boarding pass. To have your ticket checked and receive a boarding pass, proceed to the airline's check-in counter or self-service kiosk. The airline staff will verify your ticket, often scanning the barcode or QR code on it, and issue you a boarding pass. The boarding pass contains important information such as your flight number, departure time, and seat number. It serves as your permission to board the plane.

4) Once you have your boarding pass, you will proceed through passport control. Passport control is a security checkpoint where an immigration officer verifies your passport and travel documents. At passport control, you will present your passport to the officer, who will inspect it for validity and may ask you a few questions regarding your travel. The area where you put your bag and mobile phone at the airport security before going through the scanner is typically called the "security tray" or "security bin." You would place your bag and belongings, including your mobile phone, in the tray provided, which will go through the X-ray machine for security screening.

5) After passing through passport control, you will enter the departure lounge. The departure lounge is a designated area in the airport where passengers wait before boarding their flights. In the departure lounge, there are various facilities and amenities available, including shopping options like duty-free stores. Duty-free shops offer products such as perfumes, alcohol, and souvenirs with tax and customs duty exemptions, making them cheaper than usual retail prices. You can take advantage of the duty-free shopping opportunities while waiting for your flight.
