How Fast Is Commercial Airliner?

Modern airliners cruise at 250 m/s — 900 km/h. The most fuel-efficient operating range for large jets, balancing speed against air resistance. Modern airliners are 80% more fuel-efficient per passenger than 1960s jets — a quiet engineering triumph.

A modern airliner's wings flex up to 8 metres at the tip during turbulence — they are designed to bend, not resist, like a fishing rod.
