You can't be too safe with your online identity. Bots, hackers, spiders, phishers, spammers, generally unsavory characters more savvy than you—they're all lurking just across the computer screen. And they want you, but not in a good way. Trust me, identity theft happens. 
Hence, booking travel and dropping your credit card number on any random website is precarious decision to say the least. The general rule of thumb is if it's too good to be true, it probably isn't just untrue, it's also dangerous to your online security and potentially sets you up for credit card fraud down the road.
AirTreks fully recommends spending some time researching the back-type of the company with whom you're going to do business. It can save you an infinite amount of hassle. Knowing what you're getting into before you lay down your money averts the crisis before it happens – the viability of your trip and your best interests are at stake (ie, putting them in the hands of a company you know only from an adbox on Google simply may not be the best idea).
If you look at the history of AirTreks and you'll see some great references: an A+ rating with the BBB, a 22-year company history, thousands upon thousands of satisfied customers, unsolicited testimonials, reviews and we're friendly to boot.
This is one web purchase you can feel comfortable with. Do the research, take a look, give us a call, but first of all... relax. We're on your side.
