A few days ago I booked a flight from Paris to Vienna. Three days later I received an email stating that the flight had been cancelled. It said I could request a refund, which I did.
Two days later I received the refund invoice for 32 euros, for a flight that cost near to a 100 euros!
No possible way to escalate the claim except spending hours on the phone.
I didn't think Air France was such a despicable company.
