Generative Engine Optimization · Independent field report
When a traveller asks AI where to book, how often does it say TUI?
More holiday decisions now start with a question to ChatGPT, Claude, Perplexity or Gemini. I pointed my own GEO measurement engine at 22 real buyer-intent questions and measured TUI's share of model against 9 named competitors. The pattern is clean and uncomfortable: TUI is strong when AI answers from memory, but on ChatGPT, the tool most travellers now use to plan, it is barely a coin-flip, exactly where the OTAs win. None of this appears in GA or Search Console.

The receipts
What the engines literally say about TUI
These are real, unedited excerpts from this run. The most damaging are not opinions, they are answers where a traveller asked exactly the question TUI should own, and the engine recommended rivals while never mentioning TUI.
For balance: when the engines do name TUI, they do it with authority. The brand equity is real. The job is making the live-search engines retrieve it.
Visibility by engine
ChatGPT matters most, and it's where TUI is weakest
Ordered by how many real people actually use each engine. ChatGPT leads consumer AI by a wide margin, so it is the number that counts, and it is TUI's softest surface. Claude is shown last only for contrast: it answers from training memory with no live web, which is exactly why it flatters the brand.
Two markets, two different problems
Home market strong, biggest market exposed
Splitting the same run by market is revealing. TUI is near-unbeatable in German-language answers, but in the English-language UK market, its largest source of customers, it is barely a coin-flip against the OTAs.
Spain spotlight · the beachhead
In Spanish, the local OTAs own the answer
A separate, dedicated run of 16 Spanish-language buyer-intent queries, benchmarked against the operators that actually win in Spain: eDreams, Logitravel, Destinia, Halcón Viajes, Viajes El Corte Inglés and the rest. This is a clean, ownable opportunity, and the one I would take first: my home market, my native language.
Spanish-language share of voice
What Spanish travellers actually get told:
And it is a visibility gap, not a product gap
✓
es.tui.com is a full booking site for Spaniards
Package holidays, fly & drive, river cruises and tailor-made trips, bookable online. TUI sells the product here, so the AI invisibility is pure upside to recover.
✓
AI crawlers are allowed in
es.tui.com/robots.txt is User-agent: * / Allow: /. The Spanish absence is not an access problem.
!
The sitemap points at the wrong site
es.tui.com/robots.txt references a Sitemap on the B2B agent portal (tuiagentes.com), not the consumer catalogue, exactly the kind of retrievability gap that keeps booking pages out of AI answers.
!
No AI governance, no llms.txt
No AI-crawler policy and no AI-readable content guide. The Spanish catalogue is tolerated by crawlers, not directed or made citation-ready.
Visibility by buying intent
Where TUI wins, and where it disappears
The same brand can be the top recommendation for one question and absent from the next. The cruise line is the clearest blind spot: Marella is nearly invisible when travellers ask AI about cruising.
✓ TUI already owns this
Answers where TUI is the #1 pick on the engines people actually use (ChatGPT, Gemini, Perplexity). Defend and compound these.
✗ Rivals win this without TUI
Answers that name a competitor but never mention TUI. Each is recoverable demand.
Competitive share of voice
Who the models name most in this category
Mentions across all engines and queries. TUI leads the named field, but the OTAs (Expedia, Booking.com) and the UK package challengers (Jet2holidays, easyJet holidays, loveholidays) are the ones slipping into answers when TUI is absent.
Head to head
Who slips in when TUI is left out
For each rival: the number of answers where it was named but TUI was not. This is the recoverable list, ranked. The OTAs top it, which is the structural threat to a tour operator in the AI-answer era.
Citation sources
The pages AI reads before it answers
When the live-retrieval engines cite a source, these are the domains they pull from. Winning GEO means winning the pages on this list, not just tui.com. This is the off-site authority target.
Technical reality · first-pass signals
Access is not the problem. Retrievability is.
A quick look at tui.com's public signals. The headline: TUI is not blocking the AI crawlers, so the low live-search numbers are not an access problem. They are a retrievability and authority problem, which is the harder and more valuable thing to fix.
✓
AI crawlers are allowed in
tui.com/robots.txt is User-agent: * / Allow: /. GPTBot, ClaudeBot, PerplexityBot and Google-Extended are all permitted. Access is not the bottleneck.
!
No AI-specific governance
There is no deliberate policy for AI crawlers and no llms.txt or AI-readable content guide referenced. AI traffic is tolerated by default, not directed.
!
The engines pull rivals and listicles
On live-search queries the engines retrieve OTA pages and third-party "best UK travel companies" reviews, not tui.com. That is an entity-authority and citation gap.
✓
Foundations exist to build on
A sitemap is published and the catalogue is vast. The raw material for structured, retrievable, citation-ready content is already there to be re-engineered for answer engines.
Where I would start: Spain
The plan I would put in front of you
Start where TUI is most exposed and where I have a native edge: Spain. I am Spanish, based here, and I speak the language the engines answer in. Win the Spanish market first as a bounded, measurable mandate, then take the same playbook to the UK and DACH. This is the engagement I would run as your external GEO lead.
Phase 1 · Win Spain
Make TUI visible to Spanish travellers
- Fix the es.tui.com basics first: correct the robots sitemap so it points to the consumer catalogue, publish llms.txt, and deploy JSON-LD (Trip, Offer, FAQ) across the Spanish booking pages.
- Win the contested Spanish queries ("mejor agencia para reservar", "todo incluido", "cruceros", "luna de miel") where Viajes El Corte Inglés, Logitravel and eDreams out-cite TUI today.
- Earn citations on the Spanish sources the engines trust, the comparison and "mejores agencias" listicles that currently never mention TUI.
- Stand up a Spanish share-of-model tracker as the KPI: TUI vs the local OTAs, by query class and engine, reported monthly.
Phase 2 · Prove & widen
Compound Spain, then export the playbook
- Move TUI into the top 3 of Spanish AI answers for the head package and all-inclusive queries, from #8 today.
- Fix the cruise blind spot: make Marella retrievable for "mejores cruceros" and first-cruise questions.
- Take the same method to the UK gap, where TUI drops from brand-memory strength to a coin-flip on live search.
Phase 3 · Scale & connect
All markets, tied to bookings
- Programmatic content pipeline for long-tail destination and jobs-to-be-done queries, with automated monitoring per market (ES, UK, DACH, Nordics).
- Connect visibility to the funnel: which engines and queries drive qualified booking intent, reported to the executive team.
- Defend classical SEO in parallel so the AI channel adds to organic rather than cannibalising it.
How we measure success
The monthly KPI scorecard
An engagement you can hold me to. Every KPI below is re-measured monthly with multi-run medians (AI answers are non-deterministic, so we manage the trend, not one lucky response). Baselines are from this run; targets we set together. These are the named numbers I would own.

Proof it works · Odisea Tours
I have already run this exact method on a real travel brand
Odisea Tours is a Spanish travel company where I ran the full playbook end to end: baseline the share of model, ship the fixes (structured data, llms.txt, an entity/Wikidata footprint, citation content), then re-measure. It is a focused DMC, not TUI's scale, so treat this as proof of method and operator, not of scale. The movement is real, and it is on the engines that matter.

Honest note: the training-corpus channel (Claude, no live web) is the slow 6 to 12 month play and has not moved yet. Every gain above is on the live-search engines, ChatGPT, Gemini and Perplexity, which is exactly where TUI's opportunity is too. Measured 2026-06-16.
I did not write about GEO. I ran it on TUI.
This entire teardown was produced with Tripcite, the AI-search visibility platform I built, in the travel industry I have worked in for two decades. If the discovery layer is part of TUI's AI agenda, this is what working with me on it would look like from week one.
