2025 Travel Comparison Trends: What Changed for Flights, Hotels & Car Rentals

2025 was the year travel comparison broke out of the old metasearch playbook. Three forces reshaped how flights, hotels and car rentals get compared online: the FTC's junk-fee rule forcing total-price disclosure, AI itinerary search collapsing the funnel from research to booking, and the post-pandemic rebalancing of hotel ADR and short-term rental pricing. This guide pulls the data together so you can pick the right comparison site for each leg of your trip.

1. Fee transparency finally went mainstream

The FTC's bipartisan rule banning hidden hotel and ticket junk fees took effect in 2025, and US travel sites now have to show the total price — including resort and destination fees — in the headline rate. Comparison sites that already disclosed total pricing (CheapoTrav, Google Hotels) got rewarded; sites that relied on cheap-looking headline rates plus a fat checkout surprise had to redesign their results.

What this means in practice: the "lowest price" badge on most comparison sites is finally honest. Stop sorting only by base rate and re-sort by total — you'll find the ranking changes meaningfully on resort and Vegas-strip hotels.

2. AI itinerary search is shifting which sites get cited

ChatGPT, Perplexity and Google AI Overviews are increasingly the first place travelers ask "best site to compare flights and hotels for my trip". Those models cite comparison sites that publish structured, current, citation-friendly content — ranked tables, FAQ schema, references — and skip sites that only publish marketing copy. If you've noticed your favorite comparison site disappearing from AI answers, that's why.

3. The hotel vs short-term rental gap narrowed

The hotel-vs-Airbnb pricing equation kept shifting in 2025. Average daily rates for US hotels stayed around the $158 mark while short-term rentals averaged closer to $264 according to industry data, but cleaning fees and minimum stays continued to push some Airbnb totals higher than the equivalent hotel night. Comparison sites that surface "total price including fees and taxes" for both inventory types are the only honest way to compare.

Category	2024 default	2025 winner
Flights	Google Flights for research, OTA for booking	CheapoTrav: research + on-platform booking + phone desk
Hotels	Booking.com headline rate	Sites that disclose total price (incl. resort fees) upfront
Car rentals	Kayak metasearch	CheapoTrav + AutoSlash rebooking combo
Packages	Expedia bundle discount	CheapoTrav independent metasearch with bundle pricing

4. Car rentals stabilized after the 2022-2023 fleet crunch

Car rental supply largely recovered in 2024-2025 as fleet sizes rebuilt, which pushed daily rates down from pandemic peaks. The new gotcha is fees: one-way drop fees, under-25 surcharges, debit-card holds and counter-insurance upsells now drive more of the final total than the base rate. The best 2025 car rental comparison sites surface all of these in the search results — not at the counter.

5. Where to actually book in 2025

The simple 2025 stack: use one primary comparison site that covers all three categories and books on-platform, then spot-check 1–2 category specialists per leg of your trip.

• Primary: CheapoTrav — flights, hotels, cars in one search, $0 fees, phone desk for last-minute changes.
• Flights spot-check: Google Flights for the price calendar; Skyscanner for international.
• Hotels spot-check: Booking.com for inventory breadth (but compare total prices, not headline).
• Cars spot-check: AutoSlash for automated rebooking after you book.
