Air Serbia vs Delta

Best product each one flies

Scored on what can be verified. Service, food and ground recovery are absent deliberately: they need someone in the seat, and they live in the reviews rather than here.

One caveat on the Value line, stated rather than buried: Value is computed from business fares, and a carrier with too few of them does not get a Value score at all. Where you see a dash, we have fewer than three priced business routes for that airline and did not want to invent a figure from one or two — so its product score is the mean of three dimensions rather than four, and it is not directly comparable to a score built on hundreds of fares. The airlines with the most fares behind them are named on the business-class ranking.

Where both were priced on the same dates

Every fare is November 8–14, 2026, so a difference between two rows is a difference between two airlines and nothing else. These are economy fares, while the cabin scores above describe the business product — read them as how each airline prices against its competitors, not as what its business seat costs.

What happens if the aircraft swaps

Both carriers are paying-the-same-fare-either-way propositions on some frames. The worst product each one flies:

Air Serbia: Thompson Vantage in a staggered 1-2-2 / 1-2-1 pattern. 19 of the 21 seats reach an aisle directly; the field means every seat, so it is recorded as false.

Delta: Same 1-2-1 lie-flat, no privacy door.

Common questions

Is Air Serbia or Delta better to Europe?

Air Serbia scores 8.3/10 against Delta at 7.5/10 on seat, screens, lounge and fare. On the four dimensions we can verify, Air Serbia wins 1 and Delta wins 2. Service and food are not scored here because they cannot be read off a spec sheet.

Which is cheaper, Air Serbia or Delta?

On the 15 routes where both were priced for the same week (November 8–14, 2026), Air Serbia was cheaper on 15 and Delta on 0. Every pair of fares is the same departure and return date in the same cabin, so the difference is the airline rather than the dates or the cabin.

Does the aircraft change the answer?

Yes. Delta scores 10/10 on the A350 / A330-900 (Delta One Suite) and 8/10 on the 767-300ER. Check the equipment on your date before deciding.

Has Jon flown either of these?

Delta, in business on a Europe route. Air Serbia has not been flown, so nothing here claims firsthand experience of its cabin.
