Airlines and hotels personalize prices more aggressively than any other vertical. The same flight costs different amounts when searched from Tokyo, Toronto, and Tallinn. Residential proxies in each point-of-sale market reveal the actual local fare.
Use rotating residential proxies with country-level targeting for travel fare collection. Booking sites use aggressive geo-pricing and anti-bot detection -- residential IPs are the only reliable way to see localized fares at scale.

This is standard market research. Respect rate limits, avoid booking flows unless authorized, and do not collect passenger personal data.
Airlines and OTAs set fares by point-of-sale country -- the market where the booking originates. A search from the US market shows USD prices with US-market inventory. The same flight searched from the Brazilian market shows BRL prices that can differ by 30-40%. A datacenter IP gets the default market or a block.
The only reliable way to see what a real user sees is to become one.
Scheduler, proxy fetch, parser, store -- the proxy is one line in the fetch step. Everything else is pipeline you already run.
Each fare search should use a fresh IP. Do not reuse IPs across searches -- booking sites track search patterns and inflate prices for repeat queries from the same visitor.
The fare depends on where you search from, not where you fly. Target the booking site from each market where you sell or compare fares.
Travel pages are 3-5x heavier than retail product pages. Budget 5 GB per 10K checks instead of the 2.4 GB typical for retail monitoring.
Failed fetches are never billed, so your effective cost tracks the success rate you actually observe.
Airlines and OTAs set prices by point-of-sale market, the country where the search originates. A search from the US shows different fares than the same search from Japan, sometimes by 30-40% once currency and local promotions are factored in. Residential proxies in each target market reveal the actual localized fare instead of the default or a block.
Travel pages average about 500 KB each, roughly 3-5x heavier than retail product pages, since fare search results carry more scripts and inventory data per response. Budget about 5 GB per 10,000 fare checks instead of the 2.4 GB that a comparable retail price-monitoring sweep would use.
Not with residential rotation and realistic headers -- each search looks like an independent traveler browsing fares rather than a repeat visitor. That matters because booking sites track search patterns and can inflate prices for queries that look like the same person searching twice. Expect 96%+ success on major OTAs.
Collecting publicly displayed prices from booking sites is standard market research, not a legal gray area. Respect each site's rate limits, avoid automating booking flows unless specifically authorized, and never collect passenger personal data during a fare search or comparison run across markets.
