Mathematical Audit

Flight Route True Cost Formulas

Appraises the full economic cost of direct versus connecting flights by factoring in airfares, cash outlays during layovers, and the opportunity cost of travel time.

Direct Flight Total True Cost = Direct Airfare + (Direct Travel Time × Hourly Time Value)
Connecting Flight Layover Expenses = Meals Cost + Local Transit + Hotel Lodging
Connecting Flight Financial Cost = Connecting Airfare + Layover Expenses
Connecting Flight Total True Cost = Connecting Financial Cost + (Connecting Travel Time × Hourly Time Value) + Risk Premium
True Opportunity Cost Savings = Direct Flight Total True Cost - Connecting Flight Total True Cost

The Risk Premium (default $25) models the estimated economic probability and stress cost of delayed flights, missed connections, or lost checked luggage.

How to Optimize Your Flight Route Selection

1

Input direct flight parameters

Enter the ticket fare and the total door-to-door flight duration in hours for the nonstop route.

2

Input connecting flight parameters

Enter the base airfare and total travel duration (including layover hours) for the multi-leg option.

3

Add layover cash expenses

Specify expected cash spending on airport meals, terminal transit, overnight hotel stays, and estimated baggage risk value.

4

Set your hourly time value

Define a personal hourly rate to assign a monetary value to your transit and layover time.

5

Compare the True Cost results

Check whether the direct flight premium is worth the time savings, or if taking a layover yields true economic value.

Real-World Scenario Example

"A passenger compares an $800 direct flight (8 hours duration, $25/hr time value) to a $550 connecting flight (14 hours duration, 5-hour layover, $30 meals, $25 risk premium)."

Inputs

directFlightTicketPrice:800
directFlightDuration:8
connectingFlightTicketPrice:550
connectingFlightDuration:14
layoverDuration:5

Result

Direct flight true cost is $1,000. Connecting flight true cost is $955 (including $605 financial cost and $350 in travel time value). Choosing the connecting route saves $45 in true value, but requires 6 more travel hours.
