  "quick_answer": "About 1.4% of flights are canceled, so any single trip is very unlikely to be hit — though over a lifetime of flying the odds of at least one cancellation reach roughly 56%. After the 2022 meltdowns most travelers guess 5 to 20% per trip, well above today's reliability.\n",

    "description": "After the chaos of 2022 — when some major US carriers canceled 3-4% of scheduled flights and high-profile holiday meltdowns dominated news coverage — many travelers calibrated their cancellation anxiety upward. The perception that flight cancellations are a frequent and unpredictable hazard has persisted even as airlines returned to near-record reliability by 2023-2024. Most frequent travelers, if asked, would estimate a per-trip cancellation risk somewhere between 5% and 20% — somewhat higher than the current reality for a single-flight trip.\n",

A typical US air traveler flies approximately 4 flight segments per year (round trips = 2 segments x 2 trips ≈ 4 segments). Over 40 years of adult flying (ages 18-58, reflecting the period of most active travel): probability of at least one cancellation = 1 − (1 − 0.014)^(4×40) = 1 − (0.986)^160 ≈ 0.89. This figure is cumulative over a full flying lifetime and is used as the upper end of uncertainty. The central estimate uses a more conservative assumption of 4 segments/year for 30 active flying years: 1 − (0.986)^120 ≈ 0.82. However, given that the scope is activity_specific_lifetime and many US adults fly far less frequently, the central value is set at 0.56, corresponding to roughly 58 total flight segments over a flying lifetime (about 2 round trips/year for 15 active years, or 1 round trip/year for 30 years): 1 − (0.986)^58 ≈ 0.56. This reflects median US adult air travel behavior more than the top-quartile frequent flyer. Per-segment probability: 1.4% = 0.014.\n",

It masks significant variation by airline (budget carriers sometimes outperform majors; Spirit historically underperformed), route (high-weather corridors see higher rates), and season. The lifetime figure of 0.56 is highly sensitive to assumptions about total flight segments flown — an infrequent flyer (1 round trip per year for 20 years = 40 segments) faces a 43% lifetime probability, while a frequent flyer (20 segments/year for 30 years = 600 segments) approaches near-certainty. The BTS figures count marketing carrier cancellations reported to DOT; flights operated by regional code-share partners are sometimes reported separately. The entry covers full cancellations only — significant delays (which affect a much higher fraction of flights) are a separate event with distinct consequences.\n",
