I wouldn't use this company ever again. Lies, lies, and more lies. They booked our flights wrong, which meant (after numerous phone calls going nowhere), we had to fork out and purchase additional flights which cost over $1000.
Top Business Class didn't help with anything, and didn't take any responsibility at all, even though it was their fault they didn't book our flights properly.
Use this website with absolute caution... And be prepared to lose money and have terrible customer service.
