PARTLY

As of 13 August 2026, AI can only partly find the cheapest flight for your business trip.

This still needs a person who signs their name to it.

Can you do it?

What the alternative costsThe supplied tool data gives no price for a human travel-booking service, so no pound comparison is stated.

If this goes wrong: you choose a fare that is not actually cheapest or does not meet company policy, then pay more or create a booking problem when the trip is already committed.

What to actually do

  1. Hand it to a person

    The route this page recommends

    A person who owns the outcome does this end to end, worth it when the failure is dear.

  2. Use a tool built for this

    Second choice

  3. Do it yourself

    The distant third

    A chat interface, chat-fluent skill, and roughly 30 minutes until you can act on the result.

    How to actually do it

    1. Write down the trip dates, acceptable departure times, airports, cabin, baggage, connection limits and your employer's booking policy.
    2. Open a flight comparison site and the relevant airline websites, run searches using the same passenger, date, airport and baggage details, and keep the result pages open.
    3. Copy the complete fare details for plausible options, including taxes, baggage, seat charges, booking fees, flight times, stops and change or refund conditions.
    4. Paste the trip details and copied results into a chatbot with the prompt above, then ask it to separate the cheapest compliant option from the cheapest supplied option.
    5. Open the airline's checkout page for the leading option and compare the final GBP total, baggage allowance, passenger details, airports, dates and fare conditions against the AI's table.
    6. Check the leading fare against your employer's travel policy and approval route, then send the verified option to the authorised booker or book it through the approved channel.

    Prompt

    Help me compare flights for a UK business trip. Do not claim that an option is the cheapest overall unless the evidence covers the relevant airlines, airports, dates and fare types. If the data is incomplete, say that clearly.

Trip details:
- Departure airport or airports: [insert]
- Destination airport or airports: [insert]
- Outbound date and acceptable time window: [insert]
- Return date and acceptable time window: [insert]
- Number of travellers: [insert]
- Cabin required by company policy: [insert]
- Baggage required: [insert]
- Maximum stops and connection limits: [insert]
- Flexibility on dates or airports: [insert]
- Company booking or approval rules: [insert]
- Currency: GBP

I will paste flight search results below. Extract each fare, including taxes, baggage, seat charges and stated booking fees where shown. Keep outbound and return legs separate, identify the airline and airports, and record departure, arrival, stops, connection times, fare conditions, change rules and refund rules. Do not fill in missing details.

Rank the results in two lists: cheapest option that meets the stated requirements, and cheapest option overall among the supplied results. Explain any difference, flag policy conflicts and identify which facts I must check on the airline or booking site before paying. Finish with a short checklist for verifying the final price and fare conditions.

What it gets wrong

  • AI cannot see every live airline, agency and negotiated business fare unless you supply those results or give it a suitable browsing tool.
  • AI cannot guarantee that a displayed fare will still be available when you reach checkout.
  • AI can miss the cost of baggage, seats, payment fees, airport changes or restrictive fare conditions.
  • AI cannot decide whether a cheaper itinerary is acceptable under your employer's duty-of-care and travel policy.
  • The final booking, passenger details and payment remain your responsibility.

What caps this at PARTLY: real time truth, verification cost and stakes of error.

FAQ

Can ChatGPT find the cheapest business flight?
It can compare flight results and rank the cheapest option among the fares you provide. It cannot reliably prove that the result is the cheapest live fare across all airlines and booking channels, so check the leading option at checkout.
Can AI compare flights on different websites?
Yes, if you give it the results or use a browsing tool that can access those pages. Ask it to compare the full price, baggage, airports, stops and fare conditions rather than the headline fare alone.
Is it safe to let AI choose my business flight?
Use AI to shortlist and organise options, not to make an unchecked booking decision. You must confirm the final fare, passenger details, company policy, connection risk and change conditions before paying.
How do I find the cheapest flight for a work trip?
Search with the same requirements across a comparison site and the relevant airline websites, then give the complete results to AI for a structured comparison. Verify the apparent cheapest compliant fare on the airline's checkout page and use your employer's approved booking route.
