An unexpected tragedy

Here is my work of about 200-250 words, in the task said that the story had to finish with the phrase : "That was the last time she ever saw them". 

There was a group of friends that were very close to each other. They were seventeen, eighteen years old, they were about to finish school. In school breaks they gathered and talked about their lives, when they finish school and also of what would happen with them in the future.
This group was composed of three boys and two girls. The  boys were called Paul, John and Gerard; the girls were Alisson and Abie.
   The years passed by and they finished school and they had jobs. They were older but they continued seeing each other. One day they planned to go to live all together to England. And so it was, they went to the airport, the five had the tickets. Alisson said:
-I want to go to the toilet!!!
-Well, go but hurry up!!- Abbie answered.
    Alisson took her time but the plane was ten minutes earlier and was about to take off. All her friends forgot about her and entered the plane. Alisson lugagge with clothes and all, now was lost in the airport.
    Alisson got out of the toilet and she didn't find her lugagge. She went to enter in the plane and she remembred that her ticket was in her lugagge.
One week later, she was with other friends she had and were watching TV and in the news channel they had shown that a plane that was going to England crashed one month ago. That was the last time she ever saw them.
