Just dropping this advice, based on my experience. Do not pay for Air France via bank transfer. This company is completely opaque and incapable of tracking payments. Due to glitch in my bank software, I sent a double payment. They were unable to confirm receipt of the double payment or whether the double payment would be passed on to Air France. This made for one nervous week as the payment was processed at a glacial pace. Then after week of wrangling with Air France, it is now being transferred back - through Global Collect. They once again cannot confirm when they might get around to sending me back the money.
TripAdvisor won't let me post this on the Air France reviews (as the flight hasn't happened yet), so I'm dropping it here, hoping it might help other travelers.
