Observed service A carrier record shows this named operator serving this named pair, and we carry that through unchanged.
Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modeled number pass for a filed one.

Buenos Aires is large, and the road in from EZE can take longer than the last hour of the flight. Cars are not our business.
Getting from EZE into Buenos Aires
Settled in advance, so the ride into Buenos Aires costs what it said it would rather than what the cab stand says.
