How Airlines Build Direct Passenger Relationships and Maximise Ancillary Revenue — Part 2

In Part 1, we broke down the triple cost of airline intermediary dependency: GDS segment fees of up to $15 per booking, OTA commissions of 15–30%, and the suppression of ancillary revenue that averages $25 per passenger and can reach $100. Here is the operating model that addresses all three simultaneously.

Step 1: Capture Every Passenger Into a Profile You Own — Regardless of How They Booked

The critical insight for airlines is that the booking channel and the relationship channel are different things. A passenger who found you on Skyscanner and booked through Expedia can still become a direct customer — starting from the moment their booking is confirmed.

Caramel captures every passenger into a unified CRM profile the moment booking data arrives, whether from your direct site, a GDS booking, or an OTA confirmation:

• Contact details: email, WhatsApp number, country of origin, language preference
• Travel history: routes, booking class, ancillaries purchased, frequency
• Behaviour signals: how far in advance they book, whether they upgrade, whether they use the lounge
• Channel preference: does this passenger respond to WhatsApp? Email? In-app notifications?

Over successive flights, the profile deepens. A business traveller who flies Athens–Thessaloniki weekly is identified as a high-value segment and routed into a dedicated VIP engagement sequence. A leisure traveller who flies to Mykonos every August is flagged for proactive re-engagement in March before peak-season inventory fills.

You don’t need to replace OTAs to own the relationship. You just need to capture it the moment the passenger exists in your system.

Step 2: Own the Pre-Flight Window — Where Ancillary Revenue Is Made

The 72-hour window before departure is the highest-conversion CRM touchpoint available to any airline. Passengers are in travel mode — checking in mentally, finalising plans, open to relevant offers. This is where ancillary revenue is won or lost.

Caramel’s AI agent automates personalised pre-flight sequences via WhatsApp and SMS, timed and contextualised to each passenger’s profile:

72 hours before departure:

“Hi Sofia, your flight to Santorini departs Friday at 08:15. Your seat is 14C. Want to move to an exit row with extra legroom? Available for €12. [Upgrade now]”

48 hours before departure (baggage prompt):

“Quick reminder: you haven’t added checked baggage to your booking. Adding it now costs €18 — at the airport it’s €35. [Add baggage]”

24 hours before departure (check-in + upsell):

“Check-in is open for your Athens–Heraklion flight. While you’re at it: our lounge pass is €22 for the day — includes breakfast and fast Wi-Fi. [Check in now] [Add lounge access]”

2 hours before departure (ground transfer upsell):

“You land in Heraklion at 10:40. Pre-booked taxi to your hotel: €28, driver waiting with your name. [Book transfer]”

These messages run automatically, personalised to the passenger’s booked route, seat assignment, and purchase history. No manual campaign setup. No batch-and-blast. The AI agent calculates timing, selects the relevant upsell based on what hasn’t been purchased, and fires.

Airlines with mature ancillary programmes generate 30–32% of total revenue from extras. The gap between best-in-class and average is almost entirely execution in the pre-flight window.

Step 3: The Post-Flight Sequence That Turns Passengers Into Direct Bookers

The post-flight window is where the next booking is won — but most airlines waste it with a generic satisfaction survey and nothing else.

Caramel automates a post-flight sequence designed to capture the moment when a passenger’s experience is freshest and their intent for repeat travel is highest:

2 hours after landing:

“Welcome back! Hope the flight was smooth. Leave us a quick review — it means a lot to the team. [Rate your flight]”

Day 3 post-flight:

“Heading back to Mykonos this summer? August dates are already moving fast. As a returning passenger, you get priority booking access 48 hours before general sale. [View available dates]”

Day 10 post-flight (loyalty enrolment):

“You’ve now flown with us twice. Join our frequent flyer programme and your next flight earns points redeemable against any route. Takes 60 seconds. [Join now]”

Month 5 post-flight (seasonal re-engagement):

“Summer is coming. Last year you flew to Corfu in July — routes are now open for booking. Direct booking passengers get guaranteed seat selection included. [Book direct]”

The final message matters: a direct-booking incentive tied to a specific, personalised prompt performs dramatically better than generic “book direct” banner advertising. The passenger remembers the flight. The offer is relevant. The action is one tap.

Step 4: Build a Loyalty Programme Without the Legacy Infrastructure

Traditional airline frequent flyer programmes require significant technology investment: points ledgers, redemption systems, partner integrations, app development. For regional and charter airlines, this has historically been out of reach.

Caramel provides a lightweight loyalty layer that operates entirely through WhatsApp and digital wallet cards:

• Digital boarding pass loyalty stamp: every flight adds a stamp to the passenger’s Apple/Google Wallet card
• Milestone rewards: 5 flights → free seat upgrade; 10 flights → lounge access; 15 flights → companion fare
• Tier notification via WhatsApp: “You’re one flight away from Silver status — here’s what that unlocks”
• Partner rewards: connect with car rental partners, hotel partners, airport lounges to offer integrated loyalty value without building the partnerships from scratch

This infrastructure requires no app download. It lives on the passenger’s device through their wallet, and communicates through the channel they already use — WhatsApp.

For a regional airline with 200,000 passengers annually, even a 10% shift from OTA to direct bookings at zero commission generates material revenue. A functioning loyalty programme that creates switching cost makes that shift sustainable.

Step 5: Natural Language Reporting That Replaces Spreadsheet Hell

Airline revenue management and marketing teams spend enormous time pulling data. Booking curves. Load factors. Ancillary attach rates by route. Repeat passenger ratios. Campaign performance. This data exists — it’s just trapped in systems that require SQL queries, CSV exports, or analyst time to surface.

Caramel’s Natural Language Analytics gives airline operations teams direct access to their data:

• “What percentage of passengers on our Athens–Rhodes route have flown with us before?”
• “Which routes have the highest ancillary attach rates this quarter?”
• “How many passengers from last summer’s peak season haven’t booked for this summer yet?”
• “What’s our direct booking rate versus OTA booking rate by route?”
• “Which passenger segment generates the most lounge pass purchases?”

The answer arrives in seconds. No analyst required. No waiting for the monthly report.

For smaller airlines where the marketing team is two people and the revenue manager is also the head of pricing, this intelligence layer is the difference between reactive decision-making and proactive campaign execution.

What This Looks Like in Practice

Regional Greek carrier (Sky Express model): Every island-route passenger captured at booking confirmation. Pre-flight WhatsApp sequences generate 15–20% ancillary uplift per passenger. Post-flight loyalty enrolment converts 25% of repeat passengers to direct bookers within 12 months.

Charter airline (seasonal Mediterranean routes): Tour-operator passengers who cannot be captured pre-flight are contacted post-arrival. Re-engagement campaigns in winter activate direct bookings for next summer before OTA season opens. GDS dependency reduces meaningfully within two peak seasons.

Boutique/luxury airline: VIP passenger profiles enable hyper-personalised service — preferred seat automatically reserved, preferred meal flagged, ground transfer pre-arranged based on historical bookings. The AI agent handles all of this without manual intervention from the cabin crew or operations team.

The Direct Booking Flywheel for Airlines

The mechanism compounds the same way it does for car rental and real estate:

1. OTA passenger books → profile captured at confirmation
2. Pre-flight sequence runs → ancillary revenue maximised regardless of booking source
3. Post-flight sequence runs → loyalty enrolment, review capture, re-engagement
4. Next booking comes direct → zero distribution cost, full ancillary potential
5. Loyalty programme deepens → switching cost accumulates
6. Database grows → OTA dependency shrinks route by route, season by season

Airlines that begin this process now are building an asset — a proprietary passenger database with deep behavioural signals — that takes years to build but becomes increasingly impossible for competitors to replicate.

The $157 billion in annual ancillary revenue the airline industry generates exists because airlines that own the passenger relationship can offer the right product at the right moment. The airlines still surrendering that relationship to OTAs and GDS intermediaries are leaving the most valuable part of the transaction on the table.
