Wise buy on airplane dutyfree – Is it possible?

Buying duty-free products on an airplane is more than just a shopping spree at 35,000 feet — for many travelers, it’s part of the in-flight entertainment. When the in-flight movie doesn’t cut it and boredom kicks in, flipping through the airline’s duty-free catalogue can be surprisingly tempting.

But is sky shopping actually a good deal? The answer: sometimes yes, sometimes definitely not. Here are the key things to consider before swiping your card midair.

🥃 1. Check the Price Per Liter (or ml!)

That whiskey bottle or perfume might look like a steal, but always check the size of the product. Airlines often offer smaller bottles (like 50ml instead of the standard 100ml perfume, or 500ml liquor instead of 1L).
👉 Do the math: price per liter or milliliter often reveals that the deal isn’t as sweet as it seems.

💱 2. Mind the Exchange Rate Trap

Returning from vacation and stuck with leftover currency? It might seem smart to use it on duty-free chocolate or perfume — but beware:
Airlines often use less favorable exchange rates than you’d get at an airport or your home bank.
✔️ If the rate isn’t attractive, keep your money and convert it back home. Your wallet will thank you.

🧳 3. Shop on the Return Flight

If you’re eyeing something in the catalogue, don’t rush.
📌 Ask the flight attendant to show you the product.
📏 Check the actual size.
💰 Memorize the price.
Then, once you land, compare it to prices at the airport duty-free shop or in local stores.
If it’s still the best deal — buy it on your return flight.

🎯 Final Tip:

Airline duty-free can be convenient and sometimes unique, but smart travelers treat it like any other shopping experience: compare, calculate, and don’t get carried away by the altitude.
