Automate airline customer support with AI-powered FAQ responses using OpenAI, instantly answering travel questions while routing complex inquiries to human agents.
The Airlines FAQ Bot is an intelligent, AI-powered customer service automation that instantly answers passenger questions about flights, policies, bookings, and travel procedures. This workflow combines natural language processing with a knowledge base system to deliver accurate, contextual responses 24/7 without human intervention.
Key benefits include:
Ideal use cases:
This workflow is perfect for:
Why it's needed: OpenAI powers the intelligent core of your FAQ bot. The workflow uses two distinct OpenAI models: GPT-3.5-turbo for fast question classification and GPT-4 for generating detailed, contextual answers. This dual-model approach balances speed with accuracy.
Setup steps:
How to obtain API keys:
Configuration in TaskAGI:
The webhook acts as your entry point, receiving customer questions from your website, app, or support platform.
Configuration:
{
"userQuestion": "Can I change my flight date?",
"userId": "user_12345",
"sessionId": "session_abc123"
}
curl -X POST https://your-webhook-url \
-H "Content-Type: application/json" \
-d '{"userQuestion":"What is your baggage policy?","userId":"test_user"}'
Expected output: The workflow triggers and processes the question through subsequent nodes.
This node standardizes the incoming question, removing extra whitespace, special characters, and normalizing text.
Configuration:
" WHY IS MY FLIGHT DELAYED??? "
"why is my flight delayed"
Data flow: Cleaned question passes to Node 6078 (Classify Question Category)
This OpenAI node categorizes the question to route it appropriately.
Configuration:
gpt-3.5-turbo (fast and cost-effective for classification)0.3 (low creativity, consistent classifications)100 (classification requires minimal output)Example prompt:
You are a travel question classifier. Classify the following
airline customer question into one of these categories:
Baggage, Booking, Cancellation, Seating, Check-in, Loyalty, Other.
Question: [cleaned_question]
Respond with ONLY the category name.
Data flow: Classification result passes to Node 6080 (Parse Category Result)
This function extracts the category from OpenAI's response and formats it for downstream processing.
Configuration:
{
"category": "Baggage",
"confidence": 0.95,
"originalQuestion": "[from previous node]"
}
Data flow: Parsed category passes to Node 6082 (Fetch Knowledge Base Context)
This node retrieves relevant information from your knowledge base based on the question category.
Configuration:
{
"category": "[from Node 6080]",
"keywords": "[extracted from cleaned question]",
"limit": 5
}
{
"category": "Baggage",
"topic": "Checked Baggage Allowance",
"content": "Economy passengers receive 1 free checked bag up to 50 lbs..."
}
Data flow: Knowledge base context passes to Node 6084 (Generate AI Answer)
This is the primary response generator using GPT-4 for high-quality, contextual answers.
Configuration:
gpt-4 (superior reasoning and accuracy)0.7 (balanced creativity and consistency)500 (allows detailed responses)You are a helpful and friendly airlines travel assistant.
Use the provided knowledge base information to answer
customer questions accurately and courteously.
If information isn't available, suggest contacting support.
Knowledge Base: [from Node 6082]
Customer Question: [from Node 6076]
Provide a clear, friendly response.
Data flow: Generated answer passes to Node 6086 (Format Final Response)
This node structures the answer into a customer-friendly format.
Configuration:
{
"answer": "[from Node 6084]",
"category": "[from Node 6080]",
"timestamp": "[current time]",
"followUpOptions": [
"Need more help?",
"Speak with an agent"
]
}
Data flow: Formatted response passes to Node 6088 (Check User Satisfaction)
This conditional node determines if the answer satisfied the user.
Configuration:
Data flow: Splits into two paths based on satisfaction
Configuration:
{
"userId": "[from webhook]",
"status": "satisfied",
"category": "[from Node 6080]",
"timestamp": "[current time]"
}
Configuration:
{
"message": "I couldn't fully answer your question.
Would you like to connect with a support agent?",
"supportLink": "https://your-support-portal.com",
"estimatedWaitTime": "2-3 minutes"
}
This node combines both satisfaction paths into a single data stream.
Configuration:
{
"userId": "[from webhook]",
"answer": "[from Node 6086]",
"status": "[satisfied/unsatisfied]",
"supportOffered": "[boolean]",
"timestamp": "[current time]"
}
Data flow: Merged data passes to Node 6096 (Log Interaction to Database)
This HTTP request node stores the interaction for analytics and compliance.
Configuration:
{
"Content-Type": "application/json",
"Authorization": "Bearer [your-api-key]"
}
{
"userId": "[[nodes.6094.merged_data.userId]]",
"question": "[[nodes.6076.cleaned_question]]",
"category": "[[nodes.6080.category]]",
"answer": "[[nodes.6086.formatted_answer]]",
"satisfied": "[[nodes.6088.result]]",
"timestamp": "[[current_timestamp]]"
}
Data flow: Confirmation passes to Node 6098 (Send Response to User)
This final node returns the answer to the user through the webhook.
Configuration:
{
"status": "success",
"answer": "[[nodes.6086.formatted_answer]]",
"category": "[[nodes.6080.category]]",
"supportAvailable": "[[nodes.6092.support_offered]]",
"timestamp": "[[current_timestamp]]"
}
