First off, these guys call you (from a foreign country, based on the strong accent) every time they send you an email, which in itself is odd. They had sent me my booking confirmation, which included an American Airlines ticket number. A week later, I get an email "Thank you for choosing CheapBestFares! We were unable to confirm your booking." Ensued a list of possible reasons for that problem, no specific explanation, no apology. After calling American Airlines, I found out that the guys at CheapBestFares had booked me in a category that was not available and the airline flat declined the booking. This service is a joke. If you need to secure a reservation, run away from them!
