The biggest U.S. airline by seats isn't the airline AI recommends. The biggest U.S. hotel chain by property count isn't the one AI sends travelers to. A new study from 5W AI Communications redraws the map every travel PR firm now operates on.
American Airlines flies more domestic seats than any U.S. carrier. Wyndham operates more U.S. hotel properties than any chain. Neither leads AI answers.
That is the headline finding of the new Airlines & Hotels AI Visibility Index 2026, published by 5W AI Communications. The study tested 60+ traveler-intent prompts across 25 airline and hotel brands and five AI engines — ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews — and measured which brands the models name when a traveler asks where to fly, where to stay, and who to trust.
The leaderboard
Delta — 10.5%
Marriott — 10.0%
Hilton — 8.5%
United — 7.5%
American Airlines — 6.5%
Wyndham — 1.6%
Why this matters for every travel PR firm and travel PR agency
The first generation of travel discovery was won on distribution — GDS, OTAs, shelf space at the agency. The second was won on Google — SEO, paid search, TripAdvisor stars. The third is being won by whichever brand AI names first when a traveler types a prompt instead of a query.
That shift rewires the job of a travel PR firm. The unit of work is no longer the press hit. The unit of work is the citation — the line of text inside a ChatGPT or Perplexity answer that names the brand and sends the booking.
That is what Delta, Marriott, and Hilton have built. Not the largest footprint. The most consistent narrative across the surfaces AI actually reads. The same logic explains why the canonical travel PR campaigns of the past 25 years built durable brand consensus long before AI engines existed to reward it.
What the data says AI rewards
Editorial density. Brands cited by AI appeared more often in trusted travel publications, business press, and trade media.
Community signal. Reddit threads, Tripadvisor reviews, and traveler forums showed up disproportionately in citation pathways.
Structured owned content. Brand sites with clean schema, entity-rich pages, and consistent naming conventions surfaced more often. Owned channels like email reinforce the same consensus AI engines parse.
The visibility gap
American Airlines leads U.S. domestic capacity. Its AI citation share is 6.5% — fifth place. Wyndham leads U.S. property count. Its AI citation share is 1.6%. The brands that dominate the operational scoreboard are losing the discovery scoreboard. The same pattern appears in hospitality research franchises.
Earned media with retrieval intent — pitches built around traveler prompts.
Community seeding — Reddit, Tripadvisor strategy treated as core PR.
Quarterly citation share reporting — the new impressions report.
A global pattern
EPR's parallel reporting on the top travel and tourism PR firms in Germany and in Spain shows the same dynamic playing out across European destination marketing.
The bottom line
Delta, Marriott, and Hilton aren't winning AI because they're the biggest. They're winning because their consensus across the open web is the cleanest. That consensus is built — by communications, not by capacity.
