Session Storage

Cookies are saved to ~/.strider/united/ between sessions:

• cookies.json — Browser cookies
• session.json — Session metadata (login state, MileagePlus number)

Getting Started

1. Start the server and run united_login to get the login URL
2. Log in to United.com in your browser — session cookies are saved automatically
3. Run united_status to confirm authentication
4. Search flights with united_search_flights

Booking Safety

united_book requires confirm=true to actually purchase tickets. Without it, the tool returns a preview only. Never pass confirm=true without explicit user confirmation of the itinerary and total cost.

Example Workflow

1. united_login           → Get login URL
2. united_status          → Confirm logged in
3. united_search_flights  → Search ORD→SFO April 15
4. united_filter_flights  → Filter to nonstop only
5. united_select_flight   → Pick UA flight
6. united_select_seats    → Choose seat 22A
7. united_add_bags        → Add 1 checked bag
8. united_view_cart       → Review total
9. united_book            → Book (with confirm=true after user confirms)

Known Limitations

• Requires manual login (United does not support programmatic authentication)
• Browser automation may break if United updates their UI
• CAPTCHAs require manual intervention
• Payment methods must be pre-configured in your United account
