from airline.agents import booking_cancellation_agent
from airline.context import create_initial_context
from agents import Runner

ctx = create_initial_context()
ctx.flight_number = "NY802"
ctx.confirmation_number = "IR-D204"

### Flight Information Agent: Status and Rebooking

Source: https://context7.com/openai/openai-cs-agents-demo/llms.txt

Provides flight status updates and rebooking alternatives. It utilizes `flight_status_tool` and `get_matching_flights`, and can hand off to the booking agent for rebooking.

```python
from airline.agents import flight_information_agent
from airline.context import AirlineAgentChatContext, create_initial_context
from agents import Runner

ctx = create_initial_context()
ctx.flight_number = "PA441"
ctx.confirmation_number = "IR-D204"

result = await Runner.run(
    flight_information_agent,
    [{"role": "user", "content": "What is the status of my flight PA441?"}],
    context=ctx,
)
print(result.final_output)
# "Flight PA441 (Paris (CDG) to New York (JFK)) | Status: Delayed 5 hours due to weather,
#  expected departure 19:55 | Gate: B18 | Scheduled 2024-12-09 14:10 -> 2024-12-09 17:40
#  | This delay will cause a missed connection to NY802. Reaccommodation is recommended."
