Correct class of other columns in flightsData

[tpemartin]

flightsData has the following columns:

[1] "AirlineID" "ScheduleStartDate" [3] "ScheduleEndDate" "FlightNumber"
[5] "DepartureAirportID" "DepartureTime"
[7] "CodeShare" "ArrivalAirportID"
[9] "ArrivalTime" "Monday"
[11] "Tuesday" "Wednesday"
[13] "Thursday" "Friday"
[15] "Saturday" "Sunday"
[17] "UpdateTime" "VersionID"
[19] "Terminal" "num_codeShare"

If you think column "ArrivalAirportID" has wrong class, then

class(flightsData$ArrivalAirportID) # show current wrong class

# put your code line here

class(flightsData$ArrivalAirportID) # show  correct class now

You should replace # put your code line here with your answer code line that can ensure class(flightsData$ArrivalAirportID) has the right class.
