Without the right tools and methods, scraping Google Flights listings can get quite challenging. In this quick guide, we’re going to demonstrate how to scrape public data from flight pages and generate search results with Python and Google Flights API. We’ll gather all sorts of data, including price, flight time, and airline name.
Head to our blog to see the complete article with in-depth explanations and images for a visual reference.
- 1. Installing prerequisite libraries
- 2. Creating core structure
- 3. Getting the price
- 4. Getting the flight time
- 5. Getting the airline name
- 6. Final result
pip install bs4To start off, let’s create a function that will take a URL as a parameter, scrape that URL with Google Flights API (you can get a free 7-day trial for it) and return the scraped HTML:
def get_flights_html(url):
payload = {
'source': 'google',
'render': 'html',
'url': url,
}
response = requests.request(
'POST',
'https://realtime.oxylabs.io/v1/queries',
auth=('username', 'password'),
json=payload,
)
response_json = response.json()
html = response_json['results'][0]['content']
return htmlMake sure to change up USERNAME and PASSWORD with your actual Oxylabs credentials.
Next up, we’ll create a function that accepts a BeautifulSoup object created from the HTML of the whole page. This function will create and return an array of objects containing information from individual flight listings. Let’s try to form the function in such a way that makes it easily extendible if required:
def extract_flight_information_from_soup(soup_of_the_whole_page):
flight_listings = soup_of_the_whole_page.find_all('li','pIav2d')
flights = []
for listing in flight_listings:
if listing is not None:
# Add some specific data extraction here
flight = {}
flights.append(flight)
return flightsNow that we can get the HTML and have a function to hold our information extraction, we can organize both of those into one:
def extract_flights_data_from_urls(urls):
constructed_flight_results = []
for url in urls:
html = get_flights_html(url)
soup = BeautifulSoup(html,'html.parser')
flights = extract_flight_information_from_soup(soup)
constructed_flight_results.append({
'url': url,
'flight_data': flights
})
return constructed_flight_resultsThis function will take an array of URLs as a parameter and return an object of extracted flight data.
One thing left for our core is a function that takes this data and saves it as a file:
def save_results(results, filepath):
with open(filepath, 'w', encoding='utf-8') as file:
json.dump(results, file, ensure_ascii=False, indent=4)
returnWe can finish by creating a simple main function to invoke all that we’ve created so far:
def main():
results_file = 'data.json'
urls = [
'https://www.google.com/travel/flights?tfs=CBsQAhooEgoyMDI0LTA3LTI4agwIAxIIL20vMDE1NnFyDAgCEggvbS8wNGpwbBooEgoyMDI0LTA4LTAxagwIAhIIL20vMDRqcGxyDAgDEggvbS8wMTU2cUABSAFSA0VVUnABemxDalJJTkRCNVRGbDBOMU5UVEdOQlJ6aG5lRUZDUnkwdExTMHRMUzB0TFMxM1pXc3lOMEZCUVVGQlIxZ3dhRWxSUVRoaWFtTkJFZ1pWTWpnMk1qSWFDZ2lRYnhBQ0dnTkZWVkk0SEhEN2VBPT2YAQGyARIYASABKgwIAxIIL20vMDRqcGw&hl=en-US&curr=EUR&sa=X&ved=0CAoQtY0DahgKEwiAz9bF5PaEAxUAAAAAHQAAAAAQngM',

]
constructed_flight_results = extract_flights_data_from_urls(urls)
save_results(constructed_flight_results, results_file)def get_price(soup_element):
price = soup_element.find('div','BVAVmf').find('div','YMlIz').get_text()
return pricedef get_time(soup_element):
spans = soup_element.find('div','Ir0Voe').find('div','zxVSec', recursive=False).find_all('span', 'eoY5cb')
time = ""
for span in spans:
time = time + span.get_text() + "; "
return timedef get_airline(soup_element):
airline = soup_element.find('div','Ir0Voe').find('div','sSHqwe')
spans = airline.find_all('span', attrs={"class": None}, recursive=False)
result = ""
for span in spans:
result = result + span.get_text() + "; "
return resultHaving all of these functions for data extraction, we just need to add them to the place we designated earlier to finish up our code.
def extract_flight_information_from_soup(soup_of_the_whole_page):
flight_listings = soup_of_the_whole_page.find_all('li','pIav2d')
flights = []
for listing in flight_listings:
if listing is not None:
price = get_price(listing)
time = get_time(listing)
airline = get_airline(listing)
flight = {
"airline": airline,
"time": time,
"price": price
}
flights.append(flight)
return flightsIf we add all of it together, the final product should look something like this.

main()By employing Python and Oxylabs SERP Scraper API, you can easily deal with the dynamic nature of Google Flights and gather public data successfully.
