For the best results using our Sabre Global Reservations System 

The default search results display your requested date of travel along with +/- 3 Days either side of this date. However, this will only display a maximum of 9 options for each of the 7 days. If you would like to display up to 19 airfare options for your specified travel date, please uncheck the "I'm flexible with my dates" checkbox, and click the "Search Flights" button again. Should you wish to search for a specific airline, please enter up to 3 airlines in the "Preferred Airline" fields.
