        //click on pagination link

        for(int i=0;i<=allpages.size();i++)
        {
            if(allpages.contains(flight_no))
            {
                System.out.println("record exists");

                break;
            }

            else
            {
                System.out.println("eleenmt no");
                allpages.get(i).click();
            }
            }               
        }

        }

Output: Total page : 13

   pagination exist

   eleenmt no
   eleenmt no

FAILED: search_basedon_flightno

The error: org.openqa.selenium.StaleElementReferenceException: stale element reference: element is not attached to the page document (Session info: chrome=71.0.3578.98)

Answer 1

StaleElementReferenceException comes when the element is no longer available in the dom or has become stale. In order to correct it, you need to again fetch the elements and then operate on it.
For example in your case it should be:

List<WebElement> allpages=d.findElements(By.xpath("//div[@id='reportPagination_wrapper']//a"));
    System.out.println("Total page : "+allpages.size());

    if(allpages.size()>0)
    {
        System.out.println("pagination exist");

        //click on pagination link

        for(int i=0;i<=allpages.size();i++)
        {
            allpages=d.findElements(By.xpath("//div[@id='reportPagination_wrapper']//a"));
            if(allpages.contains(flight_no))
            {
                System.out.println("record exists");

                break;
            }

            else
            {
                System.out.println("eleenmt no");
                allpages.get(i).click();
            }
          }               
      }

  }
