Passage: Flying in an airplane is necessary to travel to far away destinations that are not easily accessible by other modes of transportation . Last summer , I had a girls trip to the Carribean . We had to plan our trip including booking airplane tickets and booking hotels . We arrive at the airport a few hours beforehand for an international flight . We all pack lightly with one piece of luggage . After waiting at the airport for a while , we boarded our plane . The flight attendants and crew are friendly . We find out seats and try to as comfortable in the cramped seating of a packed flight full of passengers . We try to relax , buckle up for a four hour flight . And the crew will come around with drinks and snacks . After a necessary flight , we arrive at our destination safely . Question: When can they sleep, watch tv or listen to music?
