My first thought was, 'there's a sucker born every minute'.

I just had a look at Flightstein to see what they do. So they ask you to tell them a price you got and the specific flight details etc. Then they ask you to answer some questions about preferences etc. Then a PERSON at their end tries to find you a lower price for your trip. The assumption of course is that they CAN find a lower price. They may change the airlines you will fly, the departure and arrival times, etc. in their search to find that lower price. What they will not do is guarantee you that they will find a lower price for the trip as you have shown them and the price you already have.

So what are they really guaranteeing? Well as their site says, 'our experts will beat your price or you don't pay our fee'. Now there's an offer to think about.

Gee, let me think. Does that sound like something amazing to me? Umm, no, it sounds like I could have taken another look at where I want to go and how I will get there, myself and come up with another possibility for getting there.

In other words, all they do is what any travel agent does, they do the looking for you. Whoopee.

Nothing changes in the world in regards to human nature. P. T. Barnum was right when he said it and he's till right today. 'There's a sucker born every minute.'
