Send LHR→BCN Flight Fare Alerts via Gmail (n8n + FlightPowers)

Get daily LHR → BCN flight deal alerts by Gmail—powered by n8n + FlightPowers

Stop guessing whether today’s flight price is “good.” This n8n workflow checks live LHR → BCN fares every morning for the next 30 days and emails you on Gmail when a price meets your deal criteria—so you can book faster when the numbers look right.

What this workflow does

• Runs automatically every day at 09:00 using a Schedule Trigger.
• Builds a 30-day search window by generating the next 30 departure dates, creating one search request per date.
• Searches FlightPowers for up to five one-way LHR → BCN flights per date in EUR.
• Compares results across the entire window and keeps the single cheapest fare found for all 30 days.
• Validates the deal: it alerts only if the cheapest fare is under €40 or has a Google price relation of “low”.
• Sends a Gmail email including the price, departure date, airline, Google price band, and a booking link when the criteria match.

Use cases

• You’re monitoring business travel from London Heathrow (LHR) to Barcelona (BCN) and want “book-worthy” alerts.
• You’re an automation engineer setting up a real-world price tracking workflow with n8n and FlightPowers data.
• You operate a small SaaS or ops function and want automated outbound notifications via Gmail without extra UI.

Technical details

• n8n-nodes-flightpowers (community node): requires a FlightPowers API credential (RapidAPI key works unchanged) and your LHR → BCN route.
• Gmail OAuth2 credential: sends the deal email to your configured recipient.
• Schedule Trigger for the daily 09:00 run.
• if and code nodes to evaluate the threshold (< €40 or Google “low”) and select the cheapest fare across 30 days.

Tip: Install the community node, set your route, configure Gmail, adjust the threshold and run time, then run the workflow once before activating to see today’s fare context.
