Industry report · Data as of 1. October 2026

Hospitality & Travel

AI models recommend Alltours 22 times in this vertical, but the brand does not appear in classic web search.

TUI is the most cited brand by AI assistants, although it does not lead in classic web search rankings. A notable sentiment skew emerges across the results, as AI models describe top direct tour operators in strictly neutral terms. In contrast, marketplaces and comparison portals like CHECK24 and Booking frequently receive positive recommendations from the AI.

What stands out in this industry

Achtung.app derives every observation directly from the collected numbers. It describes visibility in AI answers, not product quality.

  • Channel consensus

    3 of the 10 most-named AI brands are also among the 10 most visible brands in web search. The others lead in one channel only.

  • Leader in both channels

    CHECK24 is the most-named AI brand that is also among the 10 most visible brands in web search: #2 in AI answers, #2 in web search.

  • Largest channel asymmetry

    TUI is named 37× in AI answers and appears 3× in classic web search. AI models weight the brand more heavily than Google does.

  • Single provider dominant

    Trivago gets 82 % of its AI mentions from a single model (Gemini). The other providers rarely name the brand.

  • Web search only

    35 domains appear in classic web search but are named by no AI model. Mostly comparison portals, trade media, and established industry sites.

  • Stability

    1 of the 10 most-named AI brands appears in at least 66% of the model runs for its queries. The others may be missing on the next query; repeatable visibility is not a given, even at the top.

The 10 most visible brands in AI answers

Ranked by AI prominence, a consolidated 0–100 visibility score: how often a brand is named, across how many AI models, at what position, and in what sentiment. Two further factors (recommendation strength, momentum) cannot be measured here and remain hidden. How the score is calculated

  1. TUI

    tui.com New 76.1 Big Name

    TUI appears in 60% of queries across all four measured AI platforms, securing a higher average placement in AI responses (2.7) than in classic web search (6.3). All 37 of its recorded AI mentions are strictly neutral in sentiment.

  2. CHECK24

    check24.de 74.6 Big Name

    CHECK24 is cited in 53% of queries across all four AI platforms, showing comparable average positioning in AI outputs (4.3) and classic web search (5.5). The brand exhibits a notably positive sentiment profile, with positive AI mentions outnumbering neutral ones.

  3. Booking

    booking.com ↓2 69.9 Big Name

    Booking is referenced in 27% of queries across all four AI platforms, though it ranks higher on average in classic web search (2.0) than in AI responses (3.3). The domain shows strong reliability with a 50% run consistency and a heavily skewed sentiment profile of 17 positive against 7 neutral mentions.

  4. DERTOUR

    dertour.de New 64.8 Big Name

    DERTOUR surfaces in 27% of queries across all four AI platforms, achieving a notably higher average position in AI answers (3.6) compared to classic web search (8.3). This gap of nearly five positions indicates a much stronger prominence in generative AI outputs than in traditional search indexes.

  5. TUI Group

    tuigroup.com New 63.8 Big Name

    TUI Group is cited in 20% of queries across all four AI platforms with an average AI position of 3.2, despite failing to reach the top 10 in classic web search. This complete absence from the top traditional search results highlights a strictly AI-driven visibility profile for the enterprise domain.

Same brands, different visibility

Brands present in both channels, normalized to the per-channel peak and sorted by asymmetry. A long AI bar next to a short web-search bar means the brand is named disproportionately often by AI models even though it barely appears in organic web-search results. The reverse holds too.

Methodology

Achtung.app sends typical German-language queries for each industry to classic web search and to the active AI models. Queries are brand-free, so results show which brands surface organically. Both channels receive identical prompts so answers can be compared directly. Every brand named in the responses is extracted and consolidated on its canonical domain. The classic-web-search source is Brave Search, a Google-independent organic index.

3 runs per AI model per query; classic web search via a single top-10 fetch. Models queried: ChatGPT, Claude, Gemini, Perplexity. Platforms and infrastructure (e.g. Google Analytics, Instagram, YouTube, LinkedIn, TikTok) are excluded from the brand list because they are marketing channels, not competitors.

How Achtung.app collects, evaluates and what the method cannot do is set out in full in the methodology. Terms such as AI prominence, run consistency and GEO gap are explained in the glossary.

Frequently asked questions about this report

AI prominence is a 0–100 score built from four measured factors: in how many queries the brand is named (coverage), how many of the evaluated AI platforms cite it (breadth), where it appears in the answers (position), and how the mentions read (sentiment). Only measured values go in — no estimates.

This report is based on answers from ChatGPT, Claude, Gemini, Perplexity. Each query was asked multiple times per platform; the details are in the methodology note above.

The numbers come from the collection run of 1. October 2026. Achtung.app re-collects this report monthly; the ranking and texts are fully recomputed each time.

No. The ranking measures how visible a brand is in AI answers, not the quality of its products or services. A high AI prominence means AI assistants name the brand frequently and prominently when users ask questions in this field.

The report only lists brands that appeared in the AI answers or in the classic web search top 10 for the tested queries. If a brand is missing, it was not named for this query set; that says nothing about other topic areas. Pure platform and infrastructure domains are deliberately excluded.
