痛点：航班比价工具用虚假折扣、强制注册和邮件骚扰，用户只想要按航线设价格阈值并通过 Telegram 即时提醒。

目标用户：有国际旅行或海外家人、希望低成本监控特定航线直飞票价的旅行者和自托管用户

证据：I got tired of flight aggregators spamming my inbox with "deals" that aren't actually cheap, or requiring accounts, cookies, and app installs just to watch a single route. ... set a maximum price threshold ... receive an instant Telegram ping

变现：开源版免费引流，提供托管 SaaS 订阅（多航线、多人共享、短信/邮件通道、历史价格），或 Telegram 高级提醒与联盟返佣。

MVP：2周内做托管版：用户添加1-3条航线与阈值，后台定时调用航班API，Telegram Bot 推送，Stripe 订阅与用量限制；先不做复杂前端。

竞品：Google Flights 价格提醒、Skyscanner Price Alerts、Hopper、Jack's Flight Club、Flighty/其他航班追踪工具

摘要：作者用 Node.js/Docker 构建了开源航班价格监控 Telegram Bot FlightAlert，可按航线设 USD/EUR 阈值并在直飞票价低于阈值时推送，空闲内存 <65MB、缓存查询 <35ms。痛点真实但项目开源免费，帖中无付费意愿或收入数据，变现需靠托管订阅等增值服务。
