Is Delta or Iberia better to Europe?

Iberia scores 8.5/10 against Delta at 8/10 on seat, screens, lounge and fare. On the four dimensions we can verify, Delta wins 1 and Iberia wins 1. Service and food are not scored here because they cannot be read off a spec sheet.

Which is cheaper, Delta or Iberia?

On the 7 routes where both were priced for the same week (November 8–14, 2026), Delta was cheaper on 2 and Iberia on 5. 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. Iberia scores 10/10 on the A350 Next (Recaro CL6720) and 8/10 on the A330 / standard A350 (Stelia Solstys). Check the equipment on your date before deciding.

Has Jon flown either of these?

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

Head to head

Delta vs Iberia

Iberia scores 8.5/10 against Delta at 8/10 on seat, screens, lounge and fare.

By Jon Miksis · cabin data verified August 30, 2026 · fares for travel November 8–14, 2026

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: the cabin scores describe a business product and the fares behind Value are economy. A carrier that prices economy aggressively generally prices business the same way, but they are different products. Read Value as how an airline prices against its competitors, not as what its business seat costs.
