Why are there so many legs values?

 

Previously we included data on multi-city trips with up to 3 legs only. On Skyscanner a traveler can search for a trip consisting of up to 6 individual legs, which is reflected in the report now.

Reports will have colums up to 5 legs because these are zero indexed, e.g. Leg_5_segment_14_TravelDistanceKm is 15th seg of 6th leg,Leg_0_segment_0_ArrivalTimestamp is the 1st seg of 1st leg
