The UK Aviation society and travel industries are very closely linked especially on commercial airlines dealing with holiday makers, this is because in order for holiday maskers to travel on the airline they need to go through travel agents and tour operators to find the airline that is rite for them and to book there tickets. There are different types of airline travel that companies have to offer they are budget, scheduled, charted and cargo. It is up to the travel agents to make sure the passengers get the appropriate flight for them aka they wouldn't send a high class business man on a budget airline.
