Trend analysis for Delta Air Lines - SEA

Between 2017 and 2024, Delta Air Lines - SEA's Total Case Rate worsened from 3.5 to 4.2 recordable injuries per 100 full-time workers, a 17% increase across 7 years of OSHA reporting.

The safest year on record was 2017, at a TCR of 3.5, while 2023 saw the highest rate, at 6.7, a spread of 3.2 points between the best and worst reporting years. That's a wide swing relative to the establishment's overall rate, worth checking the year-by-year table below for whether a single severe year is driving the average, rather than a sustained trend.

Summed across those 7 reporting years, Delta Air Lines - SEA recorded 1,169 total injuries and illnesses, with no fatalities reported in any of those years. Readers comparing establishments should weigh the 7-year trend above alongside establishment size, since a larger workforce naturally accumulates more raw incidents even at a lower per-100-worker rate.

DART Rate, Transparent Calculation (2024)

DART (Days Away, Restricted, or Transferred) is computed by OSHA as incidents × 200,000 ÷ hours worked. The 200,000-hour denominator equals roughly 100 full-time workers, which lets establishments of very different sizes be compared directly.

161 DART incidents × 200,000 ÷ 8,756,943 hours worked = 3.68 DART
