Not able to select autosuggest value in input box

Hi Ashish/Team,

I was working on Question 4 (cathaypacific)given in module 17 exercise. But got stuck at one place because not able to select any value in destination input box which comes through autosuggestion. Though i am able to see value coming in but seems to not visible (As IsDisplayed() is false). Could you please help me with this?
Note : I also tried Actions.moveToElement(Element).clickAndHold().build.perform();

package qtpselenium.tutorial17;

import java.util.concurrent.TimeUnit;

import org.openqa.selenium.By;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.WebElement;
import org.openqa.selenium.chrome.ChromeDriver;

public class CopyOfExcercise_4 {
public static WebDriver driver;
public static void main(String[] args) throws InterruptedException {
System.setProperty("webdriver.chrome.driver", System.getProperty("user.dir")+"\\resources\\"+"chromedriver.exe");
driver= new ChromeDriver();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
driver.manage().window().maximize();
driver.get("http://www.cathaypacific.com/cx/en_IN.html");
driver.findElement(By.cssSelector("#depart-label")).clear();
driver.findElement(By.cssSelector("#depart-label")).sendKeys("Boston");
Thread.sleep(2000);
driver.findElement(By.xpath("//a[starts-with(@id,'ui-id') and contains(text(),Boston)]")).click();
Thread.sleep(2000);
driver.findElement(By.cssSelector("#destination-label")).clear();
Thread.sleep(1000);
driver.findElement(By.cssSelector("#destination-label")).sendKeys("London");
WebElement destination=driver.findElement(By.xpath("//*[starts-with(@id,'ui-id') and contains(text(),London)]"));
//Actions act = new Actions(driver);
//WebElement destination=driver.findElement(By.xpath("//a[starts-with(@id,'ui-id')]"));
//System.out.println(destination.isEnabled());
//System.out.println(destination.isDisplayed());
//act.moveToElement(destination).clickAndHold().build().perform();
Thread.sleep(5000);
//act.release(destination);
destination.click();

driver.findElement(By.xpath("//*[@id='book-trip-tab-panel']/div/div/form/button]")).click();
