What is the best proxy for monitoring flight and hotel prices in Asia?
Short answerThe best proxy for monitoring flight and hotel prices in Asia is a residential IP in each point-of-sale country, held on a sticky session for the length of one search, because travel sites set fares, currency and deals from the visitor's country. Jade Proxies covers 13 Asian points of sale, at $0.66/GB on the 10 GB plan.
Why do flight and hotel prices change with the visitor's country?
Flight and hotel prices change with the visitor's country because travel is sold by point of sale. Airlines file fares per country of sale and currency, and online travel agencies set the displayed currency, taxes, payment options and member deals from where the visitor appears to be. A monitoring job that runs from one server sees one point of sale; a residential IP in each country shows each market's price.
That makes travel fare monitoring a location problem first and a volume problem second. The same Bangkok–Tokyo flight or Bali hotel night can be checked from Thailand, Japan, Indonesia and Singapore in one run, with every result tagged by the country it was read from.
Which travel sites and points of sale matter in Asia?
The sites that set Asian travel prices are a mix of regional agencies and airlines, and each one is worth reading from several countries. The pairs below are examples of points of sale to compare, not a statement that prices differ on a given day.
| Site | What it sells | Points of sale to compare (examples) | Session mode |
|---|---|---|---|
| Agoda | Hotels, flights, activities | Thailand, Japan, India | Sticky from search to room page |
| Traveloka | Flights, hotels, activities | Indonesia, Vietnam, Philippines | Sticky per search |
| Trip.com | Flights, hotels, trains | Hong Kong, Singapore, South Korea | Sticky per search |
| AirAsia | Low-cost flights | Malaysia, Thailand, Indonesia | Sticky through fare selection |
| Klook | Activities, attraction tickets, transport passes | Japan, Taiwan, Singapore | Rotating for listing pages |
Jade Proxies does not sell mainland China IPs, so mainland points of sale are out of scope. For Japanese prices on Rakuten Travel or Jalan, the Japan residential proxy guide lists the ISPs and cities available.
Should you use sticky sessions or rotation for fare searches?
Use sticky sessions for fare searches and rotation for static pages. A fare search is a multi-step flow, from the search form to the results, the fare or room detail and the price summary, and travel sites tie each step to the same session cookies. Changing IP between steps can reset the search, switch the currency or return an error.
With Jade Proxies, a sticky session lasts up to 30 minutes (the IP can change earlier), which covers a search flow of a few minutes. Hotel pages, activity pages and route pages that load on their own can rotate: each new connection gets an IP from the pool, usually a different one; to get a new IP on every request, send one request per connection (turn off keep-alive).
| Step | Mode | Username example |
|---|---|---|
| Flight search on AirAsia from Malaysia | Sticky, 10 minutes | USERNAME-country-my-session-f101-ttl-10 |
| Hotel search on Agoda from Bangkok | Sticky, 15 minutes | USERNAME-country-th-city-bangkok-session-h7-ttl-15 |
| Activity listings on Klook from Japan | Rotating | USERNAME-country-jp |
Stop every flow at the price summary. Monitoring reads prices; it never holds seats, creates bookings or reserves rooms, and automated holds or resale of inventory are banned by the acceptable use policy. The rotating vs sticky guide covers session length in more depth.
How do currency and country settings interact with the proxy?
The proxy sets the country the site detects, but stored cookies and on-page settings can override it, so control all three. Start each search with a clean cookie jar, set the language and currency explicitly where the site allows it, and record with every price:
- the date and time of the reading;
- the IP country and city used;
- the currency shown and whether taxes and fees are included;
- the full search parameters (route or hotel, dates, guests, cabin).
Without these fields, two prices read from Japan and Thailand cannot be compared, because one includes tax in yen and the other excludes it in baht.
How much does fare monitoring cost per 10,000 searches?
Ten thousand fare searches cost about $1.65 to $10.40 in proxy traffic, depending on how you fetch the pages. Travel sites publish no page weights, so the figures below rest on two assumptions for planning, not measurements:
- Assumption A: 250 KB per search. Your tool calls the JSON endpoints the search page uses, without images.
- Assumption B: 2 MB per search. A headless browser loads the results and detail pages with images blocked.
The arithmetic: 10,000 searches × 250 KB = 2,500,000 KB = 2.5 GB under assumption A, and 10,000 × 2 MB = 20 GB under assumption B.
| Monitoring volume | Traffic (A: 250 KB) | Cost (A) | Traffic (B: 2 MB) | Cost (B) |
|---|---|---|---|---|
| 10,000 searches | 2.5 GB | $1.65 | 20 GB | $10.40 |
| 100,000 searches | 25 GB | $13 | 200 GB | $100 |
| 1,000,000 searches | 250 GB | $125 | 2,000 GB | $1,000 |
Rates used: 2.5 GB at $0.66/GB; 20 GB and 25 GB at $0.52/GB; 200 GB and more at $0.50/GB. Japan and Singapore cost the same per GB as Vietnam. Every plan is on the pricing page.
Why does traffic expiry matter for travel monitoring?
Traffic expiry matters because fare monitoring is seasonal: checks peak before Lunar New Year, Golden Week, Songkran, Hari Raya and the school holidays, then drop for weeks. Traffic bought for a peak and left unused is lost on a plan that resets.
According to Jade Proxies, which read 11 other residential proxy providers' own pricing pages on 13 October 2026, 6 of them sell traffic that expires, through monthly resets, a 31-day validity or 60-day credits; 4 say their traffic never expires or rolls over, and one pricing page was not read. At Jade Proxies, residential traffic never expires, so a 50 GB plan bought for the Lunar New Year peak still covers Golden Week. The residential proxy page lists the plan terms.
What are the limits of proxies for fare monitoring?
A proxy shows each point of sale's public price, not every price a traveller can get. Member-only and app-only rates need a login or the mobile app, which is outside public monitoring. Prices also move between two readings, so compare countries within the same run, not across days. City availability varies by country, and travel sites rate-limit fast clients: keep a few seconds between searches per site and back off on errors.
Frequently asked questions
Do airlines show different prices by country?
Yes. Airlines file fares per point of sale and currency, so the same flight can cost a different amount when sold in Japan or in Thailand. Exchange rates, taxes and payment fees add further gaps.
Which country IP should I use for Agoda?
Use an IP in the market whose price you report: a Thai IP for Thai customers, a Japanese IP for Japanese ones. Read the same hotel and dates from each country in the same run to compare.
Does a proxy change the currency automatically?
Often, but not always. Many travel sites pick the default currency from the IP country, while saved cookies or account settings override it. Clear cookies before each search and set the currency explicitly.
How many GB do I need for a fare monitoring test?
1 GB covers about 4,000 searches under the 250 KB assumption and lets you measure your real figure. The 1 GB plan costs $1.50, from a balance with a $25 minimum top-up.
Can I monitor Trip.com prices for mainland China?
No. Jade Proxies does not sell mainland China IPs. Trip.com's international sites can be read from Hong Kong, Taiwan, Singapore, Japan or Korea.
