+The budget for a flight is set depending on how its cost and travel time
+compares to the flight with the lowest available fare.  Travel time is
+measured from the scheduled departure time of the first flight in the
+itinerary to the scheduled landing time of the final flight.  We use the
+following table to determine the budget:
+
++--------------------------------------+------------------------------------+
+| If the travel time for a flight is…  | the budget for that flight is…     |
++--------------------------------------+------------------------------------+
+| less than three hours shorter than   | the lowest available fare + US$100 |

 Travelers may book their tickets on different dates or a different site as
 long as they used a qualifying fare search site to determine that the
