Day of the week and fares
On some routes, the day of the week that the traveler flies can affect the fare.
The letters W and X appear in the Fare Basis (letters that show the type of fare purchased).
The letter W indicates a flight departing at the Weekend, so EITHER Friday to Sunday OR Saturday and Sunday.
The letter X shows a flight departing Midweek, so EITHER Monday to Thursday OR Monday to Friday.
