• The Filter window display is shown in figure 1.9. The filters contain various ways to reduce the number of results as follows:
• Number of results displayed per page.
• Sort: by price (low to high, vice-versa), departure time (earliest to latest, vice-versa) and duration of the journey.
• Flight duration: change the time scale of the outbound time and inbound time of your flights.
• Stops: the numbers of airport connections you make between your original destination and your end location.
• Connections: long connections in stop over airports, airport transfers from one terminal to another or overnight stay.
• Airline: untick the airlines to exclude them from the search criteria.
• Filter by airport: if you have left the location open to more than one airport, filter it down to Heathrow and Gatwick to exclude London City and London Stansted
