  <p><a href="https://www.biman-airlines.com/bookings/flight_selection.aspx" rel="nofollow noreferrer">https://www.biman-airlines.com/bookings/flight_selection.aspx</a></p>
  
  <p>For example, when I choose flight from Dhaka(DAC) to  Sylhet(ZYL), it goes to </p>
  
  <p><a href="https://www.biman-airlines.com/bookings/flight_selection.aspx?TT=RT&amp;SS=&amp;RT=&amp;FL=on&amp;DC=DAC&amp;AC=ZYL&amp;AM=2018-01&amp;AD=09&amp;DC=&amp;AC=&amp;AM=&amp;AD=&amp;DC=&amp;AC=&amp;AM=&amp;AD=&amp;DC=&amp;AC=&amp;AM=&amp;AD=&amp;RM=2018-01&amp;RD=10&amp;PA=1&amp;PT=&amp;PC=&amp;PI=&amp;CC=&amp;NS=&amp;CD=&amp;FS=B4B9631" rel="nofollow noreferrer">https://www.biman-airlines.com/bookings/flight_selection.aspx?TT=RT&amp;SS=&amp;RT=&amp;FL=on&amp;DC=DAC&amp;AC=ZYL&amp;AM=2018-01&amp;AD=09&amp;DC=&amp;AC=&amp;AM=&amp;AD=&amp;DC=&amp;AC=&amp;AM=&amp;AD=&amp;DC=&amp;AC=&amp;AM=&amp;AD=&amp;RM=2018-01&amp;RD=10&amp;PA=1&amp;PT=&amp;PC=&amp;PI=&amp;CC=&amp;NS=&amp;CD=&amp;FS=B4B9631</a></p>
  
  <p>and shows the flight information</p>
  
  <p>but when I'm trying to perform such get request using python, it shows no info</p>
  
  <p>here is my code:</p>
  
  <pre><code>import requests
  
  print(requests.get('https://www.biman-airlines.com/bookings/flight_selection.aspx?TT=RT&amp;SS=&amp;RT=&amp;FL=on&amp;DC=DAC&amp;AC=ZYL&amp;AM=2018-01&amp;AD=09&amp;DC=&amp;AC=&amp;AM=&amp;AD=&amp;DC=&amp;AC=&amp;AM=&amp;AD=&amp;DC=&amp;AC=&amp;AM=&amp;AD=&amp;RM=2018-01&amp;RD=10&amp;PA=1&amp;PT=&amp;PC=&amp;PI=&amp;CC=&amp;NS=&amp;CD=&amp;FS=').text)
  </code></pre>
  
  <p>What am I doing wrong?</p>
  
  <p>thanks in advance for any help</p>
