What changes the real cost
Airfare alone hides the real tradeoff. These are the levers that move the total trip cost before payment.
| Decision point | Why it matters | Best action |
|---|---|---|
| Airport access | A cheaper airport can cost more in time and transport. | Add ground cost and reliability. |
| Route density | More options can improve timing and recovery after disruption. | Prefer schedules with backup choices. |
| Parking and transfers | Local logistics can erase fare differences. | Price the door-to-airport trip. |
| Arrival quality | The outbound airport affects the full itinerary, not only departure. | Compare both ends of the trip. |
