Leaving aside test sites or space shuttle alternates most airports built at or near sea-level have runways up to 4000m.
At 4000m any commercial airliner can take-off at any temperature (up to say 50c) at MTOW. Landing distances are almost always shorter as the aircraft is lighter.
Longer runways can be found but these are usually at elevations several thousand feet up where the thinner air causes a longer take-off run. Places like Johannesburg and Denver are good examples - the latter having runways up to 4900m (16000ft).
