This method Is intended for booking of tickets and seats on the flight.
On the stages of booking, the flight segments should be distributed is as follows:
OreginDestination=slice, Flight=segment
The flight contains 2 slice OVB->KUF and KUF->OVB (in the request there will be 2 block OreginDestination) where:
slice OVB->KUF consists of 2 segments of the OVB->DME; DME ->KUF, then the first block OreginDestination describing slice OVB->KUF, will consist of 2 blocks of the Flight, one will describe the segment, OVB->DME, and the second DME->KUF.
For slice KUF->OVB is the same.
Each of the slices may consist of any number of segments (depending on the number of transfers in).
The logic is always the same, the slice to be written as OreginDestination, inside it writable segments through Flight.
