As of 13 August 2026, AI can only partly find cheaper business travel options for your expenses.

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

What the alternative costsRows is an AI spreadsheet with live data connections and AI analysis; no human alternative price is supplied.

If this goes wrong: you choose a fare that is cheaper but unsuitable, non-refundable or outside your employer's policy.

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

How to actually do it

Open your employer's travel and expenses policy and copy the rules covering permitted suppliers, class of travel, advance booking, approval and reimbursement.
Gather the journey details, including departure and arrival points, dates, acceptable times, baggage, flexibility, accommodation and ground transport requirements.
Search the relevant airline, rail, hotel or booking sites and copy the current options into a document or spreadsheet with prices, taxes, fees, timings, links, baggage and cancellation terms.
Paste the policy, requirements and collected options into the prompt, replacing each bracketed slot with your information.
Ask the model to rank the options and identify the cheapest policy-compliant choice, then open every cited booking page and compare the live price, availability and terms with its table.
Send the selected option and the verification details to the required manager or travel approver before booking, then retain the approval and receipt with the expense record.

Prompt

Compare the business travel options below and identify the lowest-cost option that still meets the stated requirements.

Travel requirements:
- Traveller: [number of travellers]
- Departure: [airport or station]
- Destination: [airport or station]
- Outbound date and acceptable departure window: [details]
- Return date and acceptable arrival window: [details]
- Cabin or travel class allowed: [details]
- Baggage needed: [details]
- Accommodation needed: [yes or no, with location and room requirements]
- Ground transport needed: [details]
- Employer travel policy: [paste the relevant rules]
- Existing quotes or options: [paste each price, currency, supplier, link, timings, baggage, flexibility and cancellation terms]

Use only the information supplied here. Do not invent prices, availability, journey times, taxes, fees or policy rules. Separate confirmed facts from assumptions and flag missing information. Compare the total cost in pounds where the supplied data allows it, including unavoidable fees. Rank the options by total cost, then show the main trade-offs in journey time, changes, cancellation, baggage, connections and policy compliance. Do not recommend an option that breaches the policy unless you label it clearly as non-compliant. State exactly which booking pages or supplier terms I must open to verify each price and condition. Finish with the cheapest compliant option and a short checklist of what I must confirm before booking.

Open it prefilled in ChatGPT or Claude, or copy it into Gemini, which takes no prefill link.

What it gets wrong

AI cannot guarantee that a fare or room is still available when you try to book it.
It cannot know whether a cheaper route is acceptable when the policy or your work requirements leave room for judgement.
It cannot complete the booking, obtain approval or accept the financial consequences of a missed connection or non-refundable ticket.
It cannot verify supplier terms unless you provide current source information or open the booking pages yourself.

What caps this at PARTLY: real time truth, verification cost and judgement under ambiguity.

How we scored this

FAQ

Can AI find cheaper flights for a business trip?: Partly. AI can compare flight options and rank the cheapest ones when you provide current prices, timings, baggage and cancellation terms, but it cannot guarantee live availability.
Can AI check if a cheaper travel option follows my expenses policy?: Yes, if you paste the relevant policy and the full option details. You still need to confirm ambiguous rules with your employer and obtain any required approval.
Can AI book the cheapest business travel option for me?: No. It can prepare a shortlist, but you must verify the live price and terms, get approval where required and complete the booking yourself or through your approved booking channel.
Is it safe to use AI to reduce business travel costs?: It is useful for comparing supplied options, but the result is only as reliable as the current prices and terms you provide. Check the booking page before paying, because you remain responsible for policy breaches, missed travel and non-refundable costs.
