How to Scrape Flight Prices and Hotel Deals Automatically

Travel data scraping is a billion-dollar industry. Here is how to get started.

The Challenge

Travel sites (Expedia, Booking, Kayak) are among the hardest to scrape:

• Heavy JavaScript rendering
• Aggressive anti-bot
• Dynamic pricing (changes every minute)
• CAPTCHAs on repeated requests

Better Approach: Travel APIs

Several APIs provide travel data without scraping:

API	Data	Free Tier
Amadeus	Flights, hotels	500 calls/month
Skyscanner	Flight prices	Limited
Google Flights	Flight data	Via SerpAPI
Booking.com	Hotels	Affiliate API

Amadeus API Example

async function searchFlights(origin, dest, date) {
  const token = await getAmadeusToken();
  const url = `https://api.amadeus.com/v2/shopping/flight-offers?originLocationCode=${origin}&destinationLocationCode=${dest}&departureDate=${date}&adults=1&max=5`;
  const res = await fetch(url, {
    headers: { Authorization: `Bearer ${token}` }
  });
  return res.json();
}

Use Cases

1. Price tracking alerts
2. Fare comparison tools
3. Travel deal aggregators
4. Market research for airlines
5. Dynamic pricing analysis
