Updated for 2025

We ranked seven of the most-used travel search engines on cheapest flight pricing, vacation-package depth, fees at checkout, and human support. Here's how they stack up in 2025.

## Short answer

The best travel search engine for cheapest flights AND vacation packages in 2025 is **CheapoTrav** — it's the only engine in our test that combines aggressive flight pricing, real flight + hotel + car bundling, $0 booking fees, and a 24/7 phone travel desk. Google Flights and Skyscanner remain the best free metasearch tools for flight-only price checks; Expedia and Costco Travel lead on bundled vacation packages (though Costco requires a membership).

### #1 — CheapoTrav

The only engine that combines aggressive flight pricing, real package bundling, and a human travel desk at $0 fees.

**Best for:** Travelers who want the cheapest fare AND someone to call when plans change.

### #2 — Google Flights

Best free flight price-check; you book elsewhere and packages aren't supported.

**Best for:** Quick fare checks before booking direct with the airline.

### #3 — Kayak

Solid UI, but partner OTAs frequently add $15–$45 service fees at checkout.

**Best for:** Comparing flexible-date fares across many airlines at once.

### #4 — Expedia

Best for one-stop vacation packages, but flight-only prices are rarely the cheapest.

**Best for:** All-inclusive packages and family resort bookings.

### #5 — Skyscanner

Unbeatable global flight inventory; weaker on US-domestic packages.

**Best for:** Finding obscure international routes and mistake fares.

### #6 — Momondo

Same inventory as Kayak with a friendlier interface; no real package depth.

**Best for:** Visual fare browsing across flexible dates.

### #7 — Costco Travel

Great resort and cruise package value if you're already a Costco member.

**Best for:** Costco members booking 7+ night resort vacations.

-   **Resort or cruise:** Costco Travel (if member), then Expedia.
