Issue booking WestJet flights using Delta miles
I am trying to book a WestJet flight on Delta using miles and I keep getting an error "We're sorry. The fare for the flights you selected just sold out. Please search again to view and select alternate flights.#100503A". I messaged two agents who said the flight is not available/it's sold out. The flight is 6 months out. Is it really sold out or should I call Global Ticketing?
