this summer me and my friends decided to visit usa. i was so exited about this journey,and even afraided to miss the plane or forget the passport or ticket at home. so the flight day came and i packed my luggage and took my boarding card. There was a traffic jam on the wat to the airport but i catched my plane. I gave my tickets to the check-in assistant,go to the upsatirs on the escalator and find my way on the plane. In the plane there was a friendly and nice flight attendant. The plane took off and the flight was smooth and easy all the way to usa. It landed in usa at 5'o clock. I got off the plane and started my trip. But that's another story to tell:)
