mbutte, if I asked you to send a bank transfer to my account, would you? I suspect not.
Why would you consider for a microsecond giving either information or money to a website which, despite its claims, was registered on 30 August? That they do not accept 'international credit cards' is the first hint that all is not well; the 'temporary' inability to use PayPal has likely been in place since inception. The request for a bank transfer completes the hat trick.
Book with this unknown third party website if you have money to burn and wish to obtain nothing for your efforts. If you would like a safe booking experience, book directly with the airline.
