Google Flights Search
Search Google Flights via agent-browser to find flight prices, schedules, and availability.
When to Use
- User asks to search/find/compare flights or airfare
- User wants to know flight prices between cities
- User asks about flight schedules or availability
- User wants to find the cheapest flight for specific dates
When NOT to Use
- Completing purchases: This skill finds flights and extracts booking links, but do not attempt to complete a purchase on a booking site.
- Hotels/rental cars: Use other tools for non-flight travel searches.
- Historical price data: Google Flights shows current prices, not historical.
Session Convention
- Economy only (default for domestic):
--session flights - Economy + Business comparison (international or user requests):
--session econand--session biz - Interactive fallback:
--session flights
Domestic vs International Detection
Domestic flights default to economy only. Business class on US domestic routes is typically 3-5x the price and rarely worth showing unless asked.
A flight is domestic if both origin and destination are US airports. Common US IATA codes: ATL, BOS, BWI, CLT, DEN, DFW, DTW, EWR, FLL, HNL, IAD, IAH, JFK, LAS, LAX, LGA, MCO, MDW, MIA, MSP, OAK, ORD, PHL, PHX, PDX, SAN, SEA, SFO, SJC, SLC, TPA.
When to show business class:
- International flights (always show economy + business comparison)
- User explicitly asks for "business class" or "business"
- User asks to "compare cabins" or "show all classes"
When to skip business class:
- Domestic US flights (economy only by default)
- User explicitly asks for "economy" or "cheapest"
Fast Path: URL-Based Search (Preferred)
Construct a URL with a natural language ?q= parameter. Loads results directly — 3 commands total.
URL Template
https://www.google.com/travel/flights?q=Flights+from+{ORIGIN}+to+{DEST}+on+{DATE}[+returning+{DATE}][+one+way][+business+class][+N+passengers]Default: Economy Only (Domestic)
For domestic flights, run a single session - 2 tool calls total:
# Open and wait in one call
agent-browser --session flights open "https://www.google.com/travel/flights?q=Flights+from+MIA+to+SFO+on+2026-04-28+returning+2026-04-30" && agent-browser --session flights wait --load networkidle
# Snapshot results
agent-browser --session flights snapshot -i
# Keep session alive for booking linksThen present results in compact list format (see Output Format section below).
Economy + Business Comparison (International)
For international flights, run two parallel sessions to show the price delta:
# Open both and wait in parallel
(agent-browser --session econ open "https://www.google.com/travel/flights?q=Flights+from+BKK+to+NRT+on+2026-03-20+returning+2026-03-27" && agent-browser --session econ wait --load networkidle) &
(agent-browser --session biz open "https://www.google.com/travel/flights?q=Flights+from+BKK+to+NRT+on+2026-03-20+returning+2026-03-27+business+class" && agent-browser --session biz wait --load networkidle) &
wait
# Snapshot both in parallel
agent-browser --session econ snapshot -i &
agent-browser --session biz snapshot -i &
wait
# Close biz (only needed for delta); keep econ alive for booking links
agent-browser --session biz closeMatching logic: Match flights by airline name and departure time. Not all economy flights have a business equivalent (budget carriers like ZIPAIR, Air Japan don't offer business). Show "-" when no business match exists.
Tip: When an airline appears in business results but not economy (e.g., Philippine Airlines), it may operate business-only pricing on that route. Include it with "-" for economy.
One Way
Add +one+way to the URL. For international, run both economy and business in parallel:
# Domestic (economy only)
agent-browser --session flights open "https://www.google.com/travel/flights?q=Flights+from+LAX+to+JFK+on+2026-04-15+one+way" && agent-browser --session flights wait --load networkidle
# International (economy + business comparison)
(agent-browser --session econ open "https://www.google.com/travel/flights?q=Flights+from+LAX+to+LHR+on+2026-04-15+one+way" && agent-browser --session econ wait --load networkidle) &
(agent-browser --session biz open "https://www.google.com/travel/flights?q=Flights+from+LAX+to+LHR+on+2026-04-15+one+way+business+class" && agent-browser --session biz wait --load networkidle) &
waitWhen User Asks for Business Only
If the user specifically asks for business class (not a comparison), run just the business session:
agent-browser --session flights open "https://www.google.com/travel/flights?q=Flights+from+JFK+to+CDG+on+2026-06-01+returning+2026-06-15+business+class"
agent-browser --session flights wait --load networkidle

Reading Results from Snapshot
Each flight appears as a link element with a full description:

Booking Options Handoff
After presenting the results table, always offer booking links: "Want booking links for any of these? Just say which one."
When the user picks a flight, extract booking options by clicking the flight's link element in the snapshot. Google Flights shows a panel with booking providers (airlines, OTAs) each with a price and a "Continue" link to the booking site.
Workflow
# User picks flight #N — click the corresponding link from the results snapshot
# Use --session flights (domestic) or --session econ (international comparison)
agent-browser --session flights click @eN
agent-browser --session flights wait 3000
agent-browser --session flights snapshot -iThe booking panel snapshot will show link elements like:

link "Book with Booking.com THB 29,512" → href="https://..."
link "Book with Teaflight THB 28,171" → href="https://..."Extract the provider name, price, and href URL from each link.

- Session lifecycle: Keep the results session (
flightsorecon) alive for booking links. For international comparisons, close--session bizimmediately after extracting prices. Close the results session after the user gets booking links or declines. - If booking panel fails to load: Re-snapshot and wait longer before retrying.

After selecting "Multi-city" trip type, the form shows one row per leg:
- Each leg has: origin combobox, destination combobox, departure date textbox
- Origins auto-fill from the previous leg's destination
- Click "Add flight" to add more legs (default: 2 legs shown)
- Click "Remove flight from X to Y" buttons to remove legs
- Results show flights for the first leg, with prices reflecting the total multi-city cost
Fill each leg's destination + date in order, then click "Search".
Output Format
Always use compact list format — never markdown tables. Output is typically displayed in chatbot interfaces (Telegram, etc.) where tables render poorly.

- Keep the "Best value" recommendation as a plain text paragraph after the list
Key Rules
| Rule | Why |
|---|---|
| Prefer URL fast path | 2 tool calls (domestic) or 3 (international) vs 15+ interactive |
Chain open+wait with && | Eliminates a round-trip between tool calls |
| Skip business for domestic | US domestic business is 3-5x price, rarely useful unless asked |
Parallel snapshots with & + wait | Both snapshots run concurrently for international |
wait --load networkidle | Smarter than fixed wait 5000 - returns when network settles |
Use fill not type for airports | Clears existing text first |
| Wait 2s after typing airport codes | Autocomplete needs API roundtrip |
| Always CLICK suggestions, never Enter | Enter is unreliable for autocomplete |
| Re-snapshot after every interaction | DOM changes invalidate refs |
| "Done" ≠ Search | Calendar Done only closes picker |
| After presenting results, offer booking links | Users almost always want to book - prompt them |
Keep results session alive; close biz after results | Results session needed for booking clicks; biz only for delta |
Troubleshooting
Consent popups: Click "Accept all" or "Reject all" in the snapshot.
URL fast path didn't work: Fall back to interactive. Some regions/locales handle ?q= differently.
No results: Verify airports (check combobox labels), dates in the future, or wait longer.
Bot detection / CAPTCHA: Inform user. Do NOT solve CAPTCHAs. Retry after a short wait.
