Case Study: Airlines Using AI and CRM to Price Ancillaries — What Works and What's Broken

Hook: Why your bag or seat fee felt like rolling dice — and how airlines use CRM and AI-driven dynamic pricing to decide it

Travelers in 2026 rightly expect predictable fares. Instead many see erratic ancillary fees for bags and seats that jump by location, device, or even time of day. Behind that volatility are airline experiments with AI-driven dynamic pricing tied to CRM profiles. These projects can raise revenue and tailor offers — but they also expose brittle data systems, privacy trade-offs and public backlashes when models break.

Executive summary — what this case study shows

Most airlines that layered AI onto CRM and revenue-management systems achieved modest commercial gains: better ancillary attach rates, smarter upsells on high-value segments, and cleaner offers during sales. But the failures were sharp and visible: mispriced offers, elite-status mismatches, and discriminatory outcomes that led to refunds, a regulatory eyebrow or two, and permanent brand damage.

Key takeaways for travelers: watch the booking flow and total-price view, use independent flight-aggregator checks, and treat seat/bag offers as negotiable — not inevitable. For airlines: invest in unified customer IDs, real-time data governance, and human-in-the-loop guardrails before scaling AI-powered ancillaries.

Why airlines are using AI + CRM to price ancillaries now (and why it seems smart)

After years of static ancillaries, airlines saw three drivers for change in 2024–2026:

• Revenue pressure: ancillary revenue grew faster than base fares; optimizing bags/seats is a direct win.
• Better data & CRM maturity: carriers invested in customer profiles and loyalty integration.
• Distribution shifts: NDC (IATA’s New Distribution Capability) and continuous pricing pilots enabled offers outside legacy ticketing limits.

So the idea is simple: use CRM signals (loyalty tier, past spend, trip reason) + real-time context (load factor, remaining seats) to offer the right bag or seat at the right price. When it works you convert more passengers to paid ancillaries and increase perceived value.

Systems in play: what the tech stack usually looks like

• CRM: customer identity, status, past purchase history.
• Revenue Management: seat inventory, demand forecasts, fare buckets.
• Offer Engines / Dynamic Pricing Models: ML models that predict willingness-to-pay for ancillaries.
• Distribution APIs (NDC, GDS, direct): how offers reach the booking flow.
• Payment & Merchandising: checkout UX and bundling logic.

Case studies — real-world wins and failures (anonymized)

Below are anonymized case studies drawn from industry patterns, public incidents, and enterprise AI limits surfaced in research like Salesforce’s 2025–26 work on data trust.

Case A — Measured win: targeted seat offers that actually helped customers

What happened: A mid-size carrier rolled out an AI model that used CRM and trip context to offer premium seats to families and premium economy upgrades to leisure travelers near departure. The model used recency of travel, family flags (multiple passenger profiles on a single PNR), and device type to predict who would accept an offer at check-in.

Why it worked: The carrier kept data pipelines simple and fresh, ran conservative pricing bands, and conducted human review for edge cases. CRM data matched booking data in real time, so elite passengers weren’t incorrectly offered paid upgrades. The result: a meaningful lift in attach rates and lower call-center friction because families purchased seat blocks earlier.

Traveler impact: Better experiences for families who could sit together, smaller surprise charges at the gate, and offers that felt useful rather than exploitative.

Case B — Data-silo failure: elite customers charged for benefits

What happened: A large carrier deployed an AI upsell layer without full CRM integration across markets. Local check-in systems and the central CRM used different identifiers; loyalty status failed to propagate. Some elite members were offered paid baggage or seats they should have had for free.

Why it failed: Data silos and weak identity stitching. The ML model assumed CRM parity that didn’t exist in older regional systems. Complaints spiked. The carrier issued refunds and a public apology, but trust was damaged.

Traveler impact: Frustration, admin time to claim refunds, and growing skepticism about personalized offers.

Case C — Over-personalization and fairness issues

What happened: An airline’s model inferred business-traveler status from booking patterns and device usage. Business travelers consistently saw higher ancillary prices for the same seat types than others, because the model learned higher willingness-to-pay.

Why it failed: Lack of fairness constraints. The model optimized revenue without guardrails to prevent discriminatory pricing based on inferred attributes. Regulators and corporate bookers complained; some corporations threatened to move contracts.

Traveler impact: Businesses paid more; employees lost confidence in corporate travel policies; public scrutiny increased.

Case D — Technical mismatch: model drift and inventory errors

What happened: During a holiday spike, the ancillary pricing model relied on stale load factors. The system oversold premium seats when inventory rules changed, leading to seat assignment mismatches and boarding disputes.

Why it failed: Models were trained on historical patterns but lacked real-time feedback loops. No robust monitoring to detect drift or inventory reconciliation failures.

Traveler impact: Denied seating expectations and time-consuming gate-side interventions.

Why enterprise AI limits matter — lessons from Salesforce and industry research

"Enterprises continue to talk about getting more value from their data, but silos, gaps in strategy and low data trust continue to limit how far AI can scale." — Salesforce State of Data and Analytics (2025–26)

That quote sums it up. In practice this means airlines often misestimate the complexity of connecting CRM to offer engines. Three recurring issues dominate:

• Poor data quality and identity stitching: Multiple PNRs, different loyalty IDs, and regional systems break the single-customer view.
• Latency and freshness: Ancillary pricing needs millisecond-accurate inventory and status flags. Batch pipelines aren’t enough — engineers should consult real-time systems guidance when architecting reconciliation.
• Insufficient governance and explainability: Models that can’t explain why they charged more are risky when disputes arise.

Signals travelers should watch for — how to spot dynamic pricing gone wrong

• Conflicting price displays between channels (airline app vs OTA vs GDS).
• Price variation after login vs logged-out view — especially if you’re a frequent flyer.
• Unexpected add-ons for loyalty status holders (e.g., a free bag suddenly listed as paid).
• Large price spikes near check-in or immediately after booking confirmation.

Practical steps travelers can take right now

Travelers can protect pocketbooks and sanity. Below are battle-tested tactics used by professional frequent flyers and travel-savvy consumers.

Before booking

• Compare total price (fare + ancillaries). Use OTAs and direct airline pages; check the checkout flow to reveal final baggage/seat charges. Helpful tools include flight-scanner apps and aggregator checks.
• Use incognito or alternate devices to see logged-out prices — then log in to check if your loyalty status changes offers.
• Consider bundles if they consistently beat à la carte pricing for your trip profile.

After booking and before check-in

• Re-check ancillary prices 24–48 hours after booking—some airlines release cheaper seat/bag offers later to fill inventory.
• Save screenshots of price offers, receipts, and confirmation messages in case you need to dispute incorrect charges.
• If you see a mischarge (e.g., paid benefit missing), contact support immediately and request a supervisor if needed.

At the airport

• Gate agents can often override ancillary mismatches. Politely insist on the benefit your ticket grants (carry-on/checked allowances).
• For seat disputes, ask for an upgrade list or seat-reassignment options rather than paying an inflated gate fee.

How regulators and the industry are reacting in 2026

Late 2025 and early 2026 saw two important shifts:

• Regulatory scrutiny increased on opaque personalization. Authorities demanded clearer total-price displays and fairness audits for algorithmic pricing.
• Industry bodies pushed NDC and continuous offers as a way to standardize dynamic offers — but also emphasized transparency requirements to reduce consumer harm.

Expect more airlines to publish clearer ancillary calendars and to offer opt-outs for highly personalized pricing in 2026.

Advanced consumer strategies (for power users)

These tactics assume you want to minimize ancillary spend and exploit market idiosyncrasies ethically.

1. Price-compare bundling: Sometimes a slightly higher fare that includes bags and seat selection is cheaper than base fare + ancillaries. Do the math.
2. Time your purchase: For some carriers, buying seats during check-in (24–48 hours before departure) is cheaper than at booking; for others it’s the opposite. Test on repeat routes.
3. Leverage corporate or bank perks: Some credit cards and corporate programs waive baggage — use those as your baseline.
4. Use flexible alerts: Sign up for tools that monitor total-trip costs (not just base fares) and alert you when bundles dip below a threshold.

Recommendations for airlines — how to make AI + CRM work without breaking trust

If you run airline retailing, these are the non-negotiables to scale ancillaries responsibly:

• Unify identity and invest in data quality: Resolve PNR/CRM mismatches before using profiles to price offers. Practical CRM integration patterns are described in guides for teams adopting new tooling such as CRM implementation playbooks.
• Real-time reconciliation: Ensure model inputs (load, seat map, elite status) are real-time — see engineering guidance on real-time systems.
• Human-in-the-loop and explainability: Log decisions and allow manual overrides for disputed charges. Operational safety patterns overlap with modern work on agent safety and auditability.
• Fairness guardrails: Add constraints to prevent systematic overcharging of identifiable groups or inferred categories.
• Transparency in UX: Show total price early and allow customers to opt out of personalized pricing.

Future predictions — what to expect after 2026

Looking forward, several trends are likely:

• Better interoperability: Wider NDC adoption will let third parties validate offers and reduce cross-channel price divergence.
• Regulatory controls: Expect formal fairness audits and clearer consumer rights around algorithmic pricing.
• Smarter, safer personalization: Airlines that invest in governance will gain trust advantages and sustain higher ancillary yields without PR fallout.

Quick checklist — what every traveler should do now

• Always check total cost, not base fare.
• Compare logged-in vs logged-out prices.
• Screenshot offers and receipts for disputes.
• Use bundles when they beat à la carte costs.
• Leverage card and status perks to avoid extra fees.

Final thoughts

AI and CRM can make ancillary pricing smarter — and they often do. But success is not automatic. The winners in 2026 will be carriers that match technical ambition with disciplined data governance, transparent UX, and enforceable fairness constraints. Travelers can protect themselves by comparing total-trip costs, monitoring channel price differences, and asserting their rights when offers look wrong.
