July 2025

New Features

Package search (hotel + flight): Bundle up. You can now search for package deals that combine hotel + flight offers from our partners – so you save money and avoid toggling between 14 tabs.
Front door redesign: The KAYAK.ai homepage just got a glow-up. Now it helps you kick off your planning with broader travel inspo – not just specific trip tiles. Great for when you want to go somewhere, just not sure where yet.
Conceptual hotel filters: Looking for a hotel with a view of the Eiffel Tower? Or one that’s extra walkable, romantic or moody in the right way? We now support conceptual filters – even the oddly specific ones.

Fixes + Improvements

Trips Sync: Trips created in KAYAK.ai now show up in your main KAYAK Trips tab. One account, all your plans, no duplicate effort.
Car search bugs, squashed: We fixed a few weird edge cases that were messing with filters like Car Type. Car results should now behave as expected.
Smarter feedback collection: You can now tell us why something worked well when submitting positive feedback. Data is nice. Context is better.

June 2025

New Features

Sharable chat: Did all that heavy lifting? Now you can share the chat – with none of the chaos. Create a private, read-only link to your KAYAK.ai thread and let friends or family see what you’ve got planned
Flight details page: You asked for more info, so we’re giving it to you. KAYAK,ai now includes a dedicated flight details page that lets you drill into the fine print–face conditions, baggage rules, layovers, all if it. No more guesswork, especially for complex routes or deal-hunting travelers. More transparency = smarter bookings.
Package search (coming soon): Flight + hotel + not losing your mind = coming to KAYAK.ai. Stay tuned.

Fixes + Improvements

Better trip navigation: We cleaned up the Saved/Planning tab so it’s easier to jump between all the trips you’ve been mentally booking since Tuesday.
Clearer “no results” messages: When filters get too picky and return nada, we now explain why. So you can adjust and keep searching—instead of wondering if the internet broke.
Trip management – now in sticky nav: Renaming or deleting a trip? Those controls now follow you as you scroll. Because important actions shouldn’t be hiding at the top of the chat like they’re shy.
Heads-up for external links: Click a link that takes you off KAYAK.ai? We’ll give you a polite heads-up first. Not a trap—just transparency.
Bug fixes + smarter testing: Squashed some small bugs and added automated QA checks to catch the next batch before they bug you.

New Features

Car search: Looking to rent wheels for your next trip? KAYAK.ai now helps travelers search for rental cars based on specific dates and destinations. Fewer tabs, faster trips.
Multi-theme destination searches: Got range? Now you can search for places that check multiple boxes – like a “romantic, foodie-focused getaway” or “outdoorsy, budget-friendly escape.” Perfect for indecisive planners and multi-hyphenate vacations.
New feedback modal: We gave our feedback modal a glow-up. Now it’s easier to tell us what’s working – and what’s not – so we can make KAYAK.ai even smarter. (Yes, we read them. All of them.)

Fixes + Improvements

Cheapest time to travel gets smarter: When we don’t have enough data to show the cheapest time to book, we’ll now explain why – so you’re not left guessing.
Source links for AI chat responses: When KAYAK.ai answers questions that don’t involve searching (aka the “chatty” ones), we now include links to our sources. Because transparency > mystery.

New Features

Flight status: Want to know if your flight’s on time, delayed or just generally being dramatic? Ask KAYAK.ai. You can search by flight number, airline, airport or route – and skip the gate-side anxiety.
Nonstop routes: Layovers are for lunatics. See every nonstop route from any airport and get inspired for your next destination… or at least your next daydream.
Cheapest time to travel, now for Stays: KAYAK.ai now shows you when hotel prices are actually decent. Just pick a destination and we’ll surface the dates where your dollar goes the furthest.
Text summaries: Too busy to scroll? We get it. Now, before we show you the full results, KAYAK.ai gives you a quick-hit summary of what’s in store. It’s like speed dating for travel deals.

Fixes + Improvements

We squashed some post-launch bugs. RIP to weird glitches 👋
Cheapest time to travel widgets (for flights and stays) now come with shiny new CTA buttons. Because knowing when to go is great – but booking it? That’s where the magic happens.
