Book and change flights with one email
Hi there, TLDR; I built an inbox simulator so you can try BonBook in 15s, without sharing your email. Earlier this year I was flying 2-3 times per month and found booking and changing flights a hassle. So I decided to fix it. BonBook lets you find, book and change flights with one email. It can also auto-find flights for events you’re attending. Over the last few days, I built a simulator that lets you interact with BonBook without sharing your email. It responds with real flights and each response includes a link to compare w/ Google.
Book and change flights with one email launched on December 3, 2024 with 128 votes, #338 of 5,365 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
BonBook is a flight booking service that lets users find, book, and change flights through email. It automatically searches for flights to events users are attending and provides real flight options with price comparisons to Google Flights. The service is designed for frequent travelers who want to simplify the booking process. A simulator is available to test the service without sharing an email address.

Uber for Flights2025 · bookmyflight.ai · ▲12My friend and I built BookMyFlight to finally modernize flight search + booking. Why we built this: - Personalization. I fly the same route every month, and there’s no platform that knows my preferences so that I can open it, find and book my flight, and close it within a minute. - Booking is slow. I hate seeing a long clunky airline form each time I need to book. I want booking a flight to feel more like booking an Uber. How it works: 1. Optionally make an account and save your traveler preferences. Personally, I've specified my routine route as SFO to CLE and that I only want red-eye…
Travel Hacking Toolkit – Points search and trip planning with AIApr 2026 · github.com · ▲95I use points and miles for most of my travel. Every booking comes down to the same decision: use points or pay cash? To answer that, you need award availability across multiple programs, cash prices, your current balances, transfer partner ratios, and the math to compare them. I got tired of doing it manually across a dozen tabs. This toolkit teaches Claude Code and OpenCode how to do it. 7 skills (markdown files with API docs and curl examples) and 6 MCP servers (real-time tools the AI calls directly). It searches award flights across 25+ mileage programs (Seats.aero), compares cash prices…
Aruko2025 · aruko.world · ▲38A few months ago I shared my travel app here. Today I'm back with something that solved a real technical challenge I was facing. The problem: Parsing booking confirmation emails accurately. Built a parsing system that: - Distinguishes between connection hubs and actual destinations - Captures all segments (flights, hotels, trains) in the right order - Handles different booking site email formats - Creates complete itineraries automatically Happy to discuss more if anyone's interested :)
