Vietnam Airlines FAQs

Question 1

Why is my Vietnam Airlines promo code showing "invalid" during the final payment step?

Accepted Answer

Your Vietnam Airlines promo code may show as "invalid" at the final payment step if it does not meet specific eligibility criteria or if there are technical issues with the code entry. Common error messages include "Promo code invalid," "Code expired," or "This code does not apply to your booking".

Typical reasons for invalid codes:
- **Code expired**: Most Vietnam Airlines promo codes have strict purchase and travel periods (e.g., APPMAZING is valid until December 31, 2025 for international itineraries).
- **Incorrect code format**: Codes are case-sensitive and must be entered in all capital letters (e.g., APPMAZING, APPDEAL).
- **Route or fare restrictions**: Some codes only apply to specific routes, fare classes (often Economy Lite), or exclude multi-stop flights.
- **Limited daily quota**: Popular codes may reach their usage limit for the day.
- **Not applicable to taxes/fees**: Discounts typically apply only to base fares, not taxes or fees.
- **Booking method**: Some codes work only on the mobile app or website, not at ticket offices.

Step-by-step solution:
1. Double-check the code's spelling and capitalization.
2. Confirm your booking meets all promo requirements (route, fare class, travel dates, booking channel).
3. Review the promo's terms for blackout dates or excluded flights.
4. Try refreshing the page or re-entering the code.
5. If the code still fails, contact Vietnam Airlines customer support for clarification.

Pro tip: Always check the official promo terms and enter codes exactly as shown—using the app for app-exclusive codes—and book early to avoid daily quota limits.

Question 2

Can I combine multiple Vietnam Airlines promo codes on a single booking?

Accepted Answer

Vietnam Airlines does not allow the stacking or combining of multiple promo codes on a single booking; only one code can be applied per transaction.

When you enter a promo code during checkout, the system will only accept one valid code and automatically reject any additional codes. This is a standard policy for Vietnam Airlines and is enforced both on their website and mobile app.

Common scenarios:
- If you try to enter a second code, you may see an error like "Only one promo code can be applied per booking."
- Some users attempt to combine app-exclusive codes with seasonal offers, but only the first valid code is accepted.

Step-by-step solution:
1. Choose the promo code that offers the highest discount for your itinerary.
2. Enter it during the payment step.
3. If you have multiple codes, consider splitting your booking into separate transactions if possible.

Pro tip: Compare available codes before booking and select the one with the greatest value for your specific route and fare.

Question 3

Do Vietnam Airlines promo codes work on partner flights or codeshare bookings?

Accepted Answer

Vietnam Airlines promo codes generally do **not** apply to partner flights or codeshare bookings; they are restricted to flights operated directly by Vietnam Airlines.

Most promo codes specify eligible routes and fare classes, and exclude codeshare flights with partners such as Air France, Delta, or other SkyTeam members. Attempting to use a code on a codeshare segment typically results in an "invalid code" error at checkout.

Common scenarios:
- Booking a mixed itinerary with both Vietnam Airlines and a partner carrier will usually disqualify the promo code.
- Codes like APPMAZING and seasonal offers are valid only for Vietnam Airlines-operated flights departing from Vietnam.

Step-by-step solution:
1. Check your flight details to ensure all segments are operated by Vietnam Airlines.
2. Avoid adding partner flights to your booking if you want to use a promo code.
3. If unsure, look for the "operated by Vietnam Airlines" note in your itinerary.

Pro tip: Always verify the operating carrier for each flight segment before applying a promo code to avoid disappointment at checkout.

Question 4

What restrictions typically apply to Vietnam Airlines' seasonal promotion codes?

Accepted Answer

Vietnam Airlines' seasonal promotion codes come with several restrictions, including limited booking and travel periods, route exclusions, fare class limitations, and blackout dates.

Key restrictions:
- **Booking period**: Codes are valid only during specific dates (e.g., Hello Summer 2025: March 5–15, 2025).
- **Travel period**: Travel must occur within defined windows (e.g., domestic: April 5–Dec 28, 2025, excluding peak periods).
- **Route exclusions**: Certain popular routes (e.g., Hanoi-Ho Chi Minh City) are often excluded from promotions.
- **Fare class**: Discounts may apply only to Economy Lite or specific fare classes.
- **Blackout dates**: Major holidays and peak travel periods are typically excluded.
- **Booking channel**: Some codes are exclusive to the mobile app or website.
- **Limited quota**: Daily or total usage limits may apply.

Step-by-step solution:
1. Review the promo's official terms for eligible routes, dates, and fare classes.
2. Make sure your booking falls within the allowed purchase and travel periods.
3. Avoid excluded routes and blackout dates.
4. Enter the code exactly as specified and complete payment promptly.

Pro tip: Book as early as possible during the promo window and double-check all restrictions to maximize your chance of securing discounted fares.
