Why Choose VietJet Air?
VietJet Air has become one of Asia’s most popular low-cost airlines, connecting travelers to destinations across Vietnam and many international cities throughout Asia and Australia. The airline is known for its affordable fares, frequent promotional campaigns, flexible booking options, and easy-to-use online reservation system.
One of the biggest advantages of booking directly through VietJet Air is that the airline regularly offers promotional fares that can make your trip even more affordable.
If you’re planning to book a flight, it’s always worth checking for available discounts before making your payment. Our VietJet Air Coupon Code page regularly features the latest verified promotions and booking offers that can help you save on eligible flights.
Step 1: Visit the Official VietJet Air Website

The first step is to visit the official VietJet Air booking website.
Once the homepage loads, you’ll immediately see the flight booking form on the right-hand side of the page. This is where you’ll enter your travel details before searching for available flights.
You can choose between:
- Return trip
- One-way trip
- Multi-city trip
Select the option that best matches your travel plans before continuing.
Step 2: Enter Your Departure Airport
The From field is where you’ll enter your departure airport.
You can choose either:
- A domestic airport
- An international airport
Simply type the airport name or city, then select the correct airport from the list provided.
For example, if you’re departing from Hanoi, Ho Chi Minh City, Bangkok, Singapore, Sydney, or another supported destination, select the appropriate airport from the search results.
Always double-check that you’ve selected the correct airport before moving to the next step.
Step 3: Enter Your Destination
Next, click the To field.
Here you’ll enter the airport or city where you want to travel.
Just like the departure field, VietJet Air will display matching destinations as you type.
Choose your preferred destination from the available list.
Whether you’re flying within Vietnam or internationally, selecting the correct destination ensures that the search results display the available flights for your chosen route.
Step 4: Choose Your Travel Dates
Once you’ve entered your departure and destination airports, it’s time to choose your travel dates.
If you’re booking a return journey, you’ll need to select both:
- Departure date
- Return date
If you’re traveling one way, simply choose your departure date.
The booking calendar makes it easy to browse available dates and compare fares.
If your travel schedule is flexible, consider checking nearby dates as you may find lower-priced tickets during off-peak periods.
Step 5: Select the Number of Passengers

Under the passenger section, choose how many people will be traveling.
You can specify the number of:
- Adults
- Children
- Infants
Make sure the passenger information matches the identification documents you’ll use when checking in for your flight.
Entering the correct passenger count ensures accurate pricing and helps avoid changes later.
Step 6: Apply a Promotion Code

Before searching for flights, you’ll notice a Promotion Code field on the booking form.
This is where you can enter a valid VietJet Air promotional code to receive eligible discounts.
Before completing your booking, it’s a good idea to visit our VietJet Air Coupon Code page on HiCouponToday, where we regularly publish the latest verified promo codes and flight deals. If an active promotion is available, simply copy the code and paste it into the Promotion Code box before searching for flights.
Using a valid promotion code can help lower your airfare and make your trip even more affordable.
Step 7: Search for Available Flights

After entering all your travel information, click the Let’s Go or Search Flights button.
VietJet Air will display all available flights that match your search criteria.
You’ll be able to compare:
- Flight times
- Fare options
- Available seat classes
- Pricing
Take your time reviewing the available flights before selecting the one that best fits your schedule and budget.
Step 8: Review Your Booking

Once you’ve selected your preferred flight, you’ll move to the booking summary page.
Here you can review:
- Passenger details
- Travel dates
- Departure airport
- Destination
- Selected fare
- Optional baggage
- Seat selection
- Additional services
Carefully check every detail before proceeding.
Making corrections after payment may result in additional fees depending on your ticket type.
Step 9: Complete Payment
After confirming your booking information, proceed to payment.
VietJet Air supports several payment methods depending on your country and booking location.
Once your payment is successful, you’ll receive a booking confirmation by email.
Keep this confirmation safe, as you’ll need it when checking in online or at the airport.
Tips for Saving More on Your VietJet Air Booking
Finding a cheap flight isn’t only about choosing the lowest fare. A few simple habits can help you save even more.
Book your tickets early whenever possible, especially during holiday seasons when fares increase quickly.
