$653 was a price on line for 2 tickets with all taxes included. ConnectMiles price for the same flight with their "discount" was $664. I thought airlines (or the cards they offer) do not do that type of scam.
I guess they just count that no one will check the price first before calling them, so they just tell the customer on the phone that it is the best price as it is reduced to $99 + tax for second ticket and the customer is happy hearing it and never realizes he was just scammed.
