INTRODUCTION:

According to the information given in th0e question its a queue system for conducting an official activity, here we can be able to see that instead of individuals this activity is conducting for a group of people . Each group may be include two or more members, and the group may formulated for a common cause. . In the above information it is clear that they gathered in front of the airport in a queue according to the time they arrived.

In this case we can understand that the group members may decided to reach the destination ,on a specified time. .Since it is a group activity all the members need to be present for fulfilling the need. But everybody has to reach the destination for acquiring a better position in the queue but practically everybody can't reach there on the same time , because of many reason. so the group may asked the person who is residing very close to the airport to occupy the queue early to get a better position in it.  And according to the rule existed in the airport quoted in the queston that the remaining members who is coming later on can join the group members. This was the scenerio explained in the question given above.
