Proprietary Methodology

The Passenger
Trust Index™

7 dimensions. One score that tells an airline executive what their data has never been able to — what their passengers actually felt, and what it is costing them.

The Philosophy

Designed around what surveys cannot reach.

Post-flight surveys capture what passengers choose to report. Compliance audits verify whether procedures were followed. Neither instrument measures the thing that actually drives loyalty: the felt experience of being — or not being — seen, cared for, and valued as a human being in transit.

The Passenger Trust Index™ was built to measure exactly that. Every touchpoint in the framework was selected because it represents a moment where a passenger's perception of the airline either deepens or erodes — often without the passenger being consciously aware of it.

The framework does not ask whether a crew member smiled. It asks whether the passenger felt the interaction as genuine or mechanical. That distinction is the difference between a compliance audit and passenger experience intelligence.

The PTI Formula
100 − ( Total Friction Points ÷ 210 ) × 100
0 – 100
Passenger Trust Index Score
Each of the 7 dimensions is scored and weighted to produce a composite PTI Score. A perfect score of 100 represents a frictionless journey across all dimensions. Each dimension also produces an independent sub-score, enabling granular diagnosis of exactly where trust is being eroded.
Evaluation Methodology

Every touchpoint is scored
across three axes.

1
Friction Level
How much resistance, discomfort, or disappointment was present in this touchpoint. Scored 1 (no friction) to 5 (severe friction). This is the primary scoring axis and feeds directly into the PTI Score.
2
Recovery Potential
How feasible it would be for the airline to address this friction point within 90 days. Rated Low, Medium, or High effort. This axis shapes the action roadmap delivered with every report.
3
Churn Risk
How strongly this specific friction pattern correlates with passenger defection behavior. Rated Low, Medium, High, or Critical. This axis identifies which findings demand immediate leadership attention.
The Seven Dimensions

Every moment that matters.
Nothing that doesn't.

Dimension 01
The Promise
Pre-Journey
Journey Phase Booking through pre-departure — before the passenger arrives at the airport.
"Does the airline communicate as though it understands what it feels like to be a passenger preparing to fly?"
The promise is what an airline makes before a passenger ever sets foot in an airport. It is the clarity of the booking experience, the confidence of the confirmation, the helpfulness of the pre-departure communication. Most airlines underestimate how much emotional baseline is set here — and how much friction accumulated in these early moments amplifies frustration at every touchpoint that follows.
6 Evaluated Touchpoints
  • Booking flow clarity and ease
  • Confirmation and itinerary communication
  • Pre-departure notifications and reminders
  • Online and app check-in experience
  • Baggage and policy information accessibility
  • Special request handling
Dimension 02
The Approach
Ground Arrival
Journey Phase Airport arrival through check-in, bag drop, and security to the gate area.
"Does the passenger feel processed or welcomed from the moment they enter the airline's physical environment?"
The ground experience is where many airlines lose passengers before they have even boarded. Long queues without acknowledgment, check-in staff who treat passengers as entries in a system, wayfinding that assumes familiarity — these are the moments where a passenger begins to feel invisible. The Approach maps every ground touchpoint from kerb to gate area.
6 Evaluated Touchpoints
  • Signage and wayfinding clarity
  • Check-in desk staffing and wait time
  • Staff greeting and acknowledgment tone
  • Bag drop efficiency and interaction quality
  • Security liaison and airline staff presence
  • Lounge or gate area condition and comfort
Dimension 03
The Threshold
Gate Experience
Journey Phase Gate arrival through boarding — the last ground impression before the aircraft door closes.
"Is the gate agent the airline's best ambassador at its most critical transition point — or its weakest link?"
The gate is the last human moment before a passenger enters the aircraft. Gate agents can undo an excellent ground experience in a single interaction — or rescue a mediocre one. Delay communication, boarding announcement tone, and how crowding and priority seating are managed are among the highest Churn Risk touchpoints in the entire framework. This dimension alone has predicted defection in more airline engagements than any other.
6 Evaluated Touchpoints
  • Gate agent visibility and approachability
  • Boarding announcement clarity and tone
  • Delay communication — speed, honesty, empathy
  • Priority boarding execution and consistency
  • Staff demeanor during boarding congestion
  • Final pre-board passenger acknowledgment
Dimension 04
The Welcome
First 4 Minutes Aboard
Journey Phase Aircraft door to seatbelt sign — the opening emotional tone of the flight.
"In the first four minutes aboard, does the passenger feel they have arrived somewhere that was designed around them?"
Research consistently shows that the first four minutes aboard an aircraft set the emotional frame through which every subsequent interaction is interpreted. A warm door greeting followed by proactive assistance and a visible, approachable crew creates a halo effect that forgives minor friction later. Indifference at the door — a crew member looking at a manifest, no eye contact, no acknowledgment — creates a deficit that service excellence cannot easily recover.
6 Evaluated Touchpoints
  • Crew greeting at aircraft door
  • Seat area cleanliness and presentation
  • Overhead bin assistance proactivity
  • Pre-departure beverage or comfort offering
  • Safety briefing tone and engagement
  • Crew visibility and approachability pre-departure
Dimension 05
The Care Arc
In-Flight Service
Journey Phase Departure to descent — the full arc of in-flight service across the route duration.
"Does in-flight service feel designed around the passenger's journey, or around the crew's operational schedule?"
The Care Arc measures not just what service was delivered, but how it felt to receive it. The pacing of meal service, the consistency of tone across different crew members, the ratio of proactive to reactive service — these are the signals that tell a passenger whether they are being cared for or processed. A technically correct service delivered with mechanical indifference scores poorly. An imperfect service delivered with genuine warmth scores well. The distinction matters enormously to loyalty.
6 Evaluated Touchpoints
  • Meal and beverage service timing and pacing
  • Crew attentiveness between service rounds
  • Tone and language quality in every interaction
  • Passenger request response time and attitude
  • Proactive versus reactive service ratio
  • Consistency across crew members on the same flight
Dimension 06
The Truth Moment
Disruption Handling
Journey Phase Any point in the journey where something goes wrong — delay, turbulence, equipment failure, passenger incident.
"When something goes wrong, does the airline behave like a partner in the passenger's journey — or disappear?"
The Truth Moment is the single highest Churn Risk dimension in the Passenger Trust Index™. Passengers forgive problems. They do not forgive being ignored, misled, or left without information during a problem. An airline's response to disruption is the clearest possible signal of how it actually values its passengers — stripped of all the marketing language and loyalty program benefits. How a crew communicates turbulence, how a gate agent handles a delay, how a complaint is received — these are the moments that create or destroy loyalty permanently.
6 Evaluated Touchpoints
  • Delay announcement — timing, honesty, empathy
  • Turbulence communication tone
  • Equipment or service failure response
  • Passenger complaint or distress handling
  • Crew composure and professionalism under pressure
  • Resolution follow-through and closure
Dimension 07
The Last Word
Arrival & Offboarding
Journey Phase Landing through baggage claim — the final feeling a passenger carries away from the airline.
"Is the final impression the airline leaves one that makes the passenger want to return?"
The last dimension is among the most neglected in the industry. Airlines invest heavily in the boarding experience and cabin service, then allow the journey to end with an indifferent landing announcement, a chaotic disembarkation, and no meaningful farewell. The passenger's emotional memory of a flight is disproportionately shaped by how it ended — a well-established principle of behavioral psychology that most airline operational frameworks ignore entirely. The Last Word closes the loop on the full journey arc and determines the emotional residue the passenger carries to their next booking decision.
6 Evaluated Touchpoints
  • Landing and arrival announcement quality
  • Disembarkation management and communication
  • Crew farewell — presence, tone, eye contact
  • Baggage claim information accuracy
  • Post-flight communication and follow-up
  • Overall emotional residue at journey's end
Scoring Reference

The Friction Level scale.

Every touchpoint is scored 1 to 5. The scale is calibrated not against operational standards, but against the passenger's felt experience — which is the only measure that predicts loyalty.

1
Seamless
The interaction or environment felt effortless. The passenger was not aware of any friction. This is the standard every touchpoint should aspire to.
2
Minor
A small moment of inconvenience or slight disappointment. Unlikely to affect overall perception on its own, but contributes to cumulative friction patterns.
3
Noticeable
The passenger consciously registered a problem. The interaction or environment fell clearly short of reasonable expectations. Repeated at this level, loyalty begins to erode.
4
Damaging
A significant failure that creates negative emotional residue. The passenger is likely to share this experience with others or factor it into future booking decisions.
5
Critical
A severe failure that actively damages the passenger's relationship with the airline. A single score of 5 in a high-Churn Risk touchpoint is sufficient to trigger a defection-risk flag in the report.
Churn Risk Classification

Not all friction costs the same.

Every touchpoint and dimension carries a Churn Risk rating that reflects how strongly that specific failure pattern correlates with passenger defection. This classification determines priority in the action roadmap.

Low
Background Friction
Unlikely to affect loyalty on its own. Addresses quality and polish. Should be resolved in later phases of the roadmap.
Medium
Cumulative Risk
Individually manageable, but clusters of medium-risk friction create a pattern that passengers consciously register as a reason to look elsewhere.
High
Active Erosion
This friction pattern is already influencing booking decisions. Passengers experiencing this touchpoint at friction levels 3–4 are measurably more likely to defect within two flight cycles.
Critical
Defection Trigger
Immediate leadership intervention required. This friction pattern represents a structural failure in the passenger relationship that will not self-correct. Every month of delay compounds the damage.
The Friction Signature™

Your airline's fingerprint.

Every Volatrio report includes a Friction Signature™ — a visual radar chart mapped across the seven dimensions of the PTI framework. No two airlines produce the same shape. The Signature makes the finding immediately legible to a leadership team in a single glance, before a word of the report has been read.

Where the shape collapses inward toward the center of any dimension, trust is being lost. Where it holds its outer boundary, the airline is performing. The gap between where an airline's Signature sits today and where it could sit is the commercial opportunity that Volatrio exists to help close.

Signatures are tracked across repeat engagements, providing a longitudinal view of improvement — or continued erosion — over time.
