Task: Question Answering
Input (English): My wife and I flew on an airplane a couple of months ago . We were going to Las Vegas because a friend of mine was getting married . He lives there and said that he would pick us up from the airport . But , the weather here was cold and there was freezing rain , so our flight was delayed for two hours . It was kind of scary taking off because the weather was still cold and rainy , but after two hours of sitting there waiting , I was ready to go . People on the flight were pretty happy to finally leave and a lot of people were having drinks . Everyone was getting ready for their own little party in Las Vegas . The flight itself took a little over four hours due to the fact that we had a non-stop flight . I was glad I paid the extra money for not making any stops . Six hours sitting on an airplane is more than enough for me . The flight was pretty uneventful except for the lively passengers , so that was a good thing , especially since my wife hates to fly . My friend ended up still picking us up from the airport and we had a great time in Las Vegas . 
Question: How long was the plane ride?
Output (English): A little over four hours
