How To Add an Air Serbia Promo Code

Using an Air Serbia promo code is pretty straightforward once you know where to look. I checked the booking panel myself, and the good news is that the promo code field is visible right from the start — so you can add your discount before searching for flights.

• 1

  On the main booking panel, make sure the Book tab is selected. You can then choose whether you want to search for a Round trip, One way, or Multi-city ticket, depending on your travel plans.
• 2

  Fill in the From and To fields, then select your Date range and the number of Passengers. I always recommend doing this carefully before adding the code, since some promo offers only work on specific routes, travel dates, or fare types.

  On Air Serbia, the promo code box appears directly inside the main search form, just below the passenger section. That makes the process easier than on many airline sites, because you do not have to wait until the final payment step to try your code.
• 4

  Type or paste the code exactly as you found it. In my experience, it is always best to copy and paste coupon codes rather than type them manually, especially when they include a mix of capital letters and numbers.

  Air Serbia does not show a separate “Apply” button in this booking form. Instead, once your travel details and promo code are entered, click Show flights. If the code is valid, the discount should be reflected in the flight options or fare results shown on the next page.

  After the search loads, check the fare details carefully to make sure the promotion has been applied. If the discount does not appear, it usually means the code has restrictions, such as limited travel dates, selected destinations, or specific booking conditions. Once everything looks correct, continue by selecting your preferred flight, reviewing the final price, and completing your booking.
