Passage Summary: A travel agent argues that major airlines are safer because we have more data on them, while newer low-fare airlines haven't been around long enough to prove they are safe.

Conclusion: Passengers are safer traveling on major airlines than on newer low-fare airlines.

Reasoning: Low-fare airlines have short histories that make their safety records unreliable, whereas major airlines have long-standing, reliable safety records.

Analysis: The travel agent is confusing the 'reliability of data' with 'actual safety.' Just because we lack a long-term statistical track record for a new airline doesn't mean that airline is inherently dangerous; it just means we are less certain about its safety level. The flaw lies in treating a lack of proof (unreliable records) as proof of a negative (unsafe). Look for an answer that points out this confusion between the quality of evidence and the actual condition of the airlines.
