Travel data calls for residential exits targeted by country, since travel prices often depend on the visitor's market. Booking.com shows its Country Rates only to guests whose IP matches the targeted country, and airline fares can be restricted by country of sale. Sellers' pages priced country-targeted residential traffic from $0.60 per GB on October 26, 2026. The HProxy Lite pool costs $0.50 for one GB. The travel sites' own rules come first: of 12 fare sites we read, 7 closed their flight search page to all crawlers, and Booking.com's terms forbid automated access without written permission. Licensed routes exist for flights and hotels.
This page maps the work: why place matters, the rules, the licensed routes, and the per-site pages on our blog. The build guides are how to scrape flight prices and how to scrape hotel prices.
Why do travel prices depend on where you are?
Because sellers can set prices by market, and the visitor's IP is one way they tell the market. Booking.com's partner pages say Country Rates show only to guests whose IP matches the targeted country, and treat the EEA as one market. Travelport's Category 15 rules restrict the sale of a fare by "countries/currencies of sale" and by locale.
A 2017 study by Thomas Hupperich and colleagues searched the same hotels from many countries, in over 455,500 data records:
The study was run in 2017, so treat the gap as an example of the mechanism. Our page on whether proxies or VPNs get cheaper flights covers what published tests found for flights.
What do travel sites' own rules say?
Mostly no to crawlers on their search pages. We read the robots.txt files of fare and hotel sites on October 25, 2026, one search path each:
| Vertical | Search page closed | No matching rule |
|---|---|---|
| Flights, 12 sites | 7 of 12 | 5 of 12 |
| Hotels | Expedia, Hotels.com, Google, Kayak, Marriott | Booking.com pages |
Booking.com's terms say no one may "access, monitor, copy, scrape/crawl" its platform by automated means. That covers "any robot, spider, scraper, other automated means, or automated assistants", unless Booking.com gives "prior, express written permission". KAYAK's terms forbid automated tools without written permission. A proxy changes where a request comes from. It grants no permission a site has withheld.
Which licensed routes give travel prices?
Several, each with its own terms:
| Route | Vertical | Access |
|---|---|---|
| Booking.com Demand API | hotels | managed affiliates |
| Expedia Rapid API | hotels | reviewed case by case |
| Skyscanner APIs | flights | partners, by application |
| Duffel API | flights | $3.00 per order |
Our page on travel fare aggregation covers the flight routes in depth, and airline fare intelligence covers the licensed competitor data airlines buy.
Which travel pages cover each vertical?
Every page below starts from the same rules and covers one site or job.
Flights. The metasearch engines Google Flights, Skyscanner, Kayak and Momondo. The US carriers Delta, United, American, Southwest, JetBlue, Alaska and Spirit. The European carriers Lufthansa, Air France, British Airways, Ryanair and easyJet. The long-haul carriers Emirates, Qatar Airways, Singapore Airlines, Qantas and Turkish Airlines.
Hotels. The booking sites Booking.com, Expedia, Agoda, Hotels.com, Priceline, Hotwire and Trivago. The chains Marriott, Hilton, IHG, Accor, Hyatt and Wyndham. The rentals Airbnb and Vrbo. The buyer's guide is hotel rate monitoring.
Cruise, rail and car rental. The cruise lines Carnival, Royal Caribbean and Norwegian Cruise Line. The rail sellers Amtrak, Trainline and Omio. The rental companies in our car rental guide, with Hertz, Avis and Enterprise.
Across verticals. Trip.com and the price-prediction app Hopper.
What are the best residential proxies for travel price checks by market?
Pools that target the country whose prices you check, on sites that allow the visit. We read each seller's own pricing page on October 26, 2026:
| Seller | Price per GB, Oct 26 | Why it fits travel checks |
|---|---|---|
| HProxy Lite | $0.50/GB from 1 GB | country, never expires |
| Rainproxy | $0.60 at 10 GB | traffic never expires |
| Evomi | $0.99 from 15 GB | city, sticky sessions |
| DataImpulse | $1.00 from 5 GB | free country targeting |
| MarsProxies | $3.99 at 10 GB | city, sticky sessions |
| HProxy Premium | $1.45/GB from 1 GB | city, 24-hour sessions |
A logged-in account flow needs one stable address, which a static ISP address gives, and app-only checks need a mobile exit. Our best residential proxies guide compares ten sellers in full, and the free proxy checker tests an address.
What this page could not check
- Nothing measured here. We collected no travel prices and measured no seller's network, our own included.
- An older study. The hotel price figures date from 2017 and show the mechanism, not today's gaps.
- One path per site. Each robots reading checked one search path, on one day.
- Seller figures unconfirmed. The prices are those printed on October 26, 2026, and no order was placed with any seller.
- Not legal advice. Travel sites' terms and the law differ by site and country.
- Next read by January 26, 2027. Rules, partner programs and prices move, so each figure gets a fresh look by then.
