Flight search and flight status work without authentication.
1. search_flights(origin="ATL", destination="LAX", departureDate="2025-07-15")
2. get_flight_details(flightId="0")
3. select_flight(outboundFlightId="0")
4. get_seat_map()
5. select_seats(seats=["24A"])
6. add_bags(bags=1)
7. checkout() ← returns preview
8. checkout(confirm=true) ← completes purchase (needs explicit user confirmation)1. check_in(confirmationNumber="ABC123", lastName="Smith")
2. get_boarding_pass(confirmationNumber="ABC123", lastName="Smith")1. get_flight_status(flightNumber="DL 123")1. login()
2. get_skymiles()The checkout tool requires confirm: true to actually complete a purchase. Without it, the tool returns a preview of the booking details. Never set confirm: true without explicit user confirmation.
The manage_booking cancel action will prompt you to confirm on the Delta website before any cancellation is finalized.

Scored across 17 tools
Most tools have distinct purposes with clear boundaries (e.g., search_flights vs. select_flight vs. get_flight_details). However, some overlap exists: manage_booking includes 'add baggage' functionality, which could be confused with the dedicated add_bags tool, and get_booking vs. manage_booking might cause minor confusion about which to use for viewing details.
Tool names follow a highly consistent verb_noun pattern throughout (e.g., search_flights, get_booking, add_bags, select_seats). All tools use snake_case with clear, descriptive verbs, making the set predictable and easy to understand.
With 17 tools, the count is well-suited for a comprehensive airline operations server. It covers the full booking lifecycle (search, select, checkout), management (get_booking, manage_booking), check-in (check_in, get_boarding_pass), and account features (login, get_skymiles), without feeling bloated or sparse.
The toolset provides complete coverage for Delta Air Lines operations: flight search and booking (search_flights, select_flight, checkout), booking management (get_booking, manage_booking), check-in and boarding (check_in, get_boarding_pass, get_seat_map, select_seats), flight details and status (get_flight_details, get_flight_status), account management (login, logout, status, get_skymiles), and extras (add_bags, get_trip_extras). No obvious gaps exist for core airline workflows.
