What changes

For high-cost international itineraries, insurance can reduce catastrophic cancellation losses substantially—though average travelers may not claim.

When this tends to work

  • Conditions similar to: International trips over $3,000, cancellation-prone itineraries, 2019–2024
  • You can measure Out-of-pocket loss on cancelled international trips reliably
  • The intervention is implemented consistently, not half-measured

When to be careful

  • Your audience or product differs materially from the cited context
  • Compliance costs or second-order effects outweigh the lift
  • Evidence label is estimate—treat wide ranges as planning bands, not promises

Practical takeaway

Use the cited range for prioritization and test design. Verify against your own data before scaling.
