Head to head

KLM vs TAP Air Portugal

TAP Air Portugal scores 9/10 against KLM 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.
