Do not use Flights24.com website. Would that I had read the negative reviews before booking a flight on Singapore Airlines from LAX to Tokyo-Narita. After booking, I received an email requesting a copy of my passport and a copy of my credit card, front and back, and no answer to my questions via email. No answer to the telephone that is supposed to be the "hotline" for flights24.com ticket sales. I have no idea if my credit card has been charged or not. This is my worst experience on the internet ever! They take your money and run and no way to communicate.
