AI 产品解读Flight price comparison browser extension that automatically detects flight searches on competitor booking sites and notifies users when Trip.com offers a cheaper price for the same or similar flight.
Travelers waste time manually comparing flight prices across multiple booking sites. This extension automates price comparison while users browse their usual flight booking sites, surfacing cheaper Trip.com deals passively.
1. User installs extension. 2. User browses competitor flight booking sites normally. 3. Content script (content/index.js) + interceptor (content/interceptor.js) intercept fetch/XHR responses on Booking, eDreams, Expedia, Kiwi, Priceline, etc. to extract flight details and pricing. 4. Flight data is sent via postMessage to content script, relayed to background service worker. 5. Background.js calls fly.trip.com/checkPriceV3 with intercepted flight data. 6. If Trip.com offers a better price, a notification/overlay appears showing savings. 7. User clicks 'Book Now' to complete booking on Trip.com.

- 目标用户
- Online travelers searching for flights who want to find better deals without manually comparing across sites / Budget-conscious travelers looking for cheaper flight options
- Source code is heavily minified/webpack-bundled making precise line-by-line analysis of popup logic difficult
- Cannot fully verify the complete sign-in flow behavior without runtime testing
- The popup minisite_main.js (1.7MB) is too large to fully inspect, so some popup-specific behaviors may be missed
付费分析未识别到付费功能
The extension is explicitly described as 'Completely free'. No payment processing, billing APIs, subscription gates, or upgrade UI found in the source code. The 'checkout' keyword hit relates to interceptor.js intercepting Expedia/eDreams flight checkout pages to extract pricing data, not extension payment. 'Secure Payment' and 'premium' references in locale/lang files describe Trip.com destination service features (insurance premium, Premium Economy cabin class), not extension paid tiers. No stripe, license, or payment platform code detected.

- The core product workflow — detecting flight searches on competitor sites and comparing prices via Trip.com — works without any login. The background.js uses a hardcoded authorization header ('ade5f8beb741') and a generated anonymous fly_uid GUID stored in chrome.storage. The 'Sign In' button (popup_header_signin) and 'My Bookings'/'Profile' links exist in the popup for Trip.com account features (us.trip.com/order/all, us.trip.com/membersinfo/profile/) but are not required for the price comparison functionality.
This plugin actually works! It popped up a window and directed me to their website when I was trying to check out my flight to Osaka on Expedia. The plugin offered me the exact same flight that I just selected and it was about 60 bucks cheaper! Definitely would recommend anyone to use this plugin since it worked for me at least.
I think everyone should use this Plugin. 👍 For me, it helped me save about £33 when I was about to book my flights on the other site. It silently reminded me of a lower & better offer. And on top of it, I also earned cash back. So, I guess I save about £38. 😂 That's an incredible savings for my short haul flight! Thanks!
very useful.can help get lowest price.thanks!
Great function, thanks!
I like how it compares the ticket price for me. It really helps to get cheaper tickets.
사이트에 따로 가지않아도 바로 가젯에서 바로 검색할 수 있어 편리함
So Convenient,yeah!!!!
It took me a while to figure out how to this works, but it helped me at the right moment. When I was about to enter all my details on another website to place my booking, this tool suddenly showed up and offered me the EXACT same ticket for a better price. Lovely! Thanks guys!
It saved me much time to compare ticket prices between different websites, and would directly show me if there is a cheaper price on trip.com. Very nice!
Easy to use. Saved money.
