Service Suffix

SERVICE_SUFFIX

VARCHAR (16777216)

A code assigned by the administrating carrier for operational purposes.

 

Flight Number

 

 

FLIGHT_NUMBER

VARCHAR (16777216)

The four digit flight number of the leg.

Departure Airport

DEPARTURE_AIRPORT

VARCHAR (16777216)

The departure port code as assigned by IATA e.g. JFK.

 

Arrival Airport
